work these out in terms of pie

radius of 7cm and height of 12cm (work out in terms of pi)

I assume you want the volume in terms of pi

So we have

Vc = pi * r^2 * h

Vc = pi * (7)^2 * 12  =  pi * 588 =   588pi cm^3

eismax13.....the other two are worked  just the same.....see if you can do them....

thanks so much

No prob....
