A cone is placed inside a cylinder as shown. The radius of the cone is half the radius of the cylinder. The height of the cone is equal to the radius of the cylinder. What is the volume of the cone in terms of the radius, r?
Hi there, the cone is radius=1/r and h=r, the volume of the cone is 22/7*1/r*1/r*r=22/7*1/r=22/7r. Therefore, the answer is 22/7r
