Consider the solid S described below.
A right circular cone with height 7h and base radius 2r
Find the volume V of this solid
Use the standard formula for a cone.
V = (1/3) pi*r^2*h
It makes no sense to call the height 7h and the radius 2r, unless you are comparing two different cones.
h and r are the height and radius, respectively
This is not calculus
It's calculus and it's in my homework.
