The formula for the volume of a right cone (and pyramid) is 1/3 base x height, therefore the volume of this cone is :

Base = 3 x 3 x pi

Height = 9

Volume = 27 x pi, or roughly 84.8 units squared

Note: On a math test or quiz, you will lose marks for not saying units squared.

Volume of the largest possible right circular cylinder that can be inscribed in a sphere of radius a?

volume of a regular right circular cylinder is V=pi(r2)h since the radius is (a) then the height of the circular cylinder would be (2a) so the volume of the largest possible right circular cylinder is... V=2(pi)(r2)(a) with (pi) being 3.14159 with (r) being the radius of the circle on the top and bottom of the cylinder with (a) being the radius of the sphere
