# Thread: volume and surface area of circular prism

1. ## volume and surface area of circular prism

Can someone give me the steps I have to take to find the volume and surface area of a circular prism please? (what do I put into a calculator) I have the answers but need to know how to do it myself. The volume is 1848 cm, the s/a is 836 cm. The height of the prism is 12cm and the radius 7cm.

2. $SA = 2\pi r(r+h)$

$r = 7, h=12$

$SA = 2\pi \times 7(7+12) = \cdots$

$V = \pi r^2h$

$r = 7, h=12$

$V = \pi \times7^2\times12 = \cdots$

3. Thankyou so much!!
