Okay, I need a quick answer pls! I am reciting this example from a Tafe construction book:
To calculate the surface area of a cylinder having a height of 2.100m and a base radius of 850mm:
Area= (I cant find pie symbol on my computer!) (pie x radius squared) + (2x pie x radius x height)
= (3.142x 0.723x 2) + (2x 3.142x 0.850 x 2.100)
= 4.540 + 11.217= 15.757 m 2
Now… I get the formula. But how where the hell does the "0.723" as the "radius squared" come from??
Can anyone help by tonight pls? Or…. an easier way (PLEASE??) to work out the volume of a cylinder?
(Eg: How much concrete is needed for 2 colums 600mm in diametre x 4.95 high??
Hi Misty,
Its been a long time since I've looked at any maths, but here is what I think. The volume of a cylinder is end area x height. The end area of a circle is pi x (radius squared) which is 3.142 x radius x radius.
In your example the radius is 850 mm, which is 0.85 meters so the radius squared is 0.85 x 0.85 = 0.7225. Rounded up this is the 0.723 in your example.
I think For a 600mm by 4.95 m column the formula would be:
(3.142 x (0.6 x 0.6)) x 4.95
= (3.142 x 0.36) x 4.95
= (1.13112 x 4.95)
= 5.60 cubic meters for each column
That is for the volume of a cylinder, to calculate the surface area which you have taked about in your question is a different thing. For that you need the area of the ends calculated as pi x (radius squared) [x 2 if you want to count both ends]. To get the surface area of the walls of the cylinder you need the circumference of the end x the height of the cylinder. The circumferance is pi x diameter ( or pi x radius x 2).
The volume of a cylinder is measured in cubic meters and the surface area is calculated in square meters.
Hope this makes sense.

They cannot predict the growth and they told me average growth is 9% for past 10 years, a little higher than your number, so I guess that's accurate. I'm also look forward to talking to a buy's agent, can I known which one you engaged?Thanks,

– Is it a good place to live? why did you choose to live in Sunbury?
I think its a good place to live. Coming from Bendigo and resisting a move to Melbourne for as long as possible Sunbury seemed like a good place for a country lad like me. We knew some people who lived here so we had spent a small amount of time in Sunbury. We originally rented for a while before we bought a block of land and built here. It still has a bit of the big country town feel about it which suits me, but I know that it puts a lot of people off because they think it is "out in the sticks".
gaga1227 wrote:– What's the most inconvenient thing living in Sunbury? Is it just the transport and distance?I don't really find anything inconvenient about living here, but many people complain about the public transport. I think wherever you go people will be complaining about the public transport. The trains from Sunbury are V/Line so they don't run as regularly as Met trains, but that has improved a lot in the last 2 years.
It has been said that there isn't much to do for younger people (15-25 year olds) in Sunbury and there has been some talk about youth related problems, although I have never noticed that.
I think the area really suits people starting a family and those with younger children and that seems to be the types of people that are coming to Sunbury.

Median House Price 1994: $110,000
Median House Price 2004: $240,000
118% increase.I don't know how accurate these figures are and I know that in that 10 year time frame there was a lot of new land released and a lot of new houses built which I seem to recall skews the figures somehow.
gaga1227 wrote:– Why did you choose Ipswich instead? Is it because of the low growth?The main reason we wanted to invest in Sunbury was because it was going to be our first IP and we wanted something close to home to get the hang of investing. We offered on one place but didn't get it and then a buyer's agent that we had engaged showed us the place in Ipswich which we liked. We had thought we might get something in Queensland eventually so we thought we might as well get our first IP there. Now that we have our first property our main reason for investing in Sunbury has gone so it is likely our second won't be in Sunbury. I'm keen to build an IP at some stage so when I'm ready to do that I will look at Sunbury again because I would like to build somewhere close by.
Because of the low growth and the fact that there is still a fair amount of land to be released I don't think I need to rush to buy something in Sunbury.

I prefer new house because of depreciation. The property I'm considering is around 260k.I'm not sure about the big growth but tend to believe it will. Last year's 1% growing is horrible but innormal I think. What about the average growth in 10 years? Maybe last year is the bottom of the curve, maybe from last year till now most investors only interested in eastern suburbs…
Those are really helpful information and I will do some more work on it, thanks.

Do you know the name of the estate where you are looking to buy and is it through one of the local real estate agents or directly though a builder? Have you spoken to one of the property managers in Sunbury that aren't affiliated with whoever you are buying through?
Hi Johnny,
I live in Sunbury and was recently looking here to buy our first IP. We ended up buying a place in Ipswich instead but I have spent the last couple of months talking to property managers and real estate agents in Sunbury. I take it that you don't live in Sunbury so if you have any specific question let me know and I'll see if I can answer them.
Is there any reason why you are looking at buying an off the plan place rather than one of the newer established houses or completed house and land packages that are around? There is a newish estate in Sunbury that has a few houses under 4 or 5 years old for between $250K and $280K, I'm not sure how much the place is that you are looking at.
There was an article in the local paper this week about Sunbury's stagnating house prices saying that the median price only rose 0.9% in the last financial year from $251,000 to $252,250. The article blamed oversupply, high petrol prices and interest rates.
From speaking with the property managers here it does seem that rental demand is strong at the moment, but they always add the proviso "at the moment, can't guarantee how it will be in 2 months time when you settle". I also found that the rent estimates from various property managers seemed to vary quite a bit.
The train travel to Melbourne from Sunbury is generally 45-50 minutes for most peak time trains. There are a few Bendigo trains stopping in Sunbury that take around 30-35 minutes.
1 square is about 9.29 square meters, so 12 squares is around 111sq m
