I think A

aveline · Answer

The volume of a cylinder is πr^2h
The radius, r, is 10m; the height, h, is 8m

aveline · Answer

It's not going to be A, rather, 10 squared is 100, times 8 is 800
So D

@Eboogie4 
it is not A - and giving an unexplained guess like that is not useful

@MrNood Was tryin to help don't tag me in anything else btw

mrnood · Answer

thanks for what - someone gave you the answer - did oyu learn how to do it?

jojo12g · Answer

ook can u explain it to me then please

mrnood · Answer

@Aveline  gave you the formula

a cyclinder is a case of prism' so you calculate the area of the end face and multiply by the height to get the volume

The area is pi r^2
The heigh tis h

The volume of a cylinder is πr^2h
The radius, r, is 10m; the height, h, is 8m
