Homework Help: Geometry

Posted by DANIELLE on Monday, July 9, 2007 at 1:10pm.

Can someone please check these for me. I have to leave answers in Pi.

Find the Volume of a right cone with radius 6 height 10
V=1/3 pi r squared*h
=1/3pi (6)^2(10)
=1/3(360)pi
=120pi

Find the volume of a sphere with radius 3cm
V=4/3 pi r^3
=4/3 pi3^3
=4/3(27)pi
=36pi


They appear correct, but you should add that the second answer is the volume in cubic centimeters. You do not specify the measurement dimensions of the cone, for some reason.
