cylinder fits inside a square prism as shown. For every cross section, the ratio of the area of the circle to the area of the square is or nr^2 or n/4. Since the area of the circle is n/4 the area of the square, the volume of the cylinder equals
A) pi/2 the volume of the prism or pi/2(2r)(h) or pi*r*h
B) pi/2 the volume of the prism or pi/2 (4r^2)(h) or 2*pi*r*h.
C) pi/4 the volume of the prism or pi/4(2r)(h) or pi/4*r^2*h.
D) pi/4 the volume of the prism or pi/4(4r^2)(h) or pi*r^2*h
