Volume of a spa pool

Hi there,
I have a question that requires working out the volume of a spa pool.
The diametre is 2m and the pool depth is 90cm. Am I correct in these calculations?
:pi:r2 x h
ie.e 3.14 x 100 x 100 x 90 = 2826000cm3
(seems a way out there answer)
then to calculate the water required to fill the pool I divided by 1000 to get 2826 litres.
Help please, not really sure here

Hi NickC,

Assuming your spa pool is a cylinder then you are correct.
