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 i
s equal to the radius of the cylinder. What is the volume of the cone in terms of the radius, r?
1 answer:
R = radius of cone
2r = radius of cylinder
Then height of cone is 2r.
Volume of Cone is Pi * r^2 * 2r = 2Pi*r^3

For this question I’m pretty sure you have to multiply Base X height to find the area of this equation.
(32 ft) x (30 ft + 5/12 ft) = (960 ft² + 13-1/3 ft²) = 973-1/3 feet²
Answer:
