Question

A cylinder with a radius of 1 cm and a height of 21 cm has the same volume as a cone with a height of 7 cm. What is the radius of the cone?

Answer 1

The volume of cylinders. In the earlier lesson, you learned that the volume of the rectangular prism is found by multiplying the area of the base by the height of the prism. ... Example 1. This cylinder has a radius of 4 cm and a height of 10 cm. Find its volume. V = B • h. V = (π • r • r) • h. V = (3.14 • 4 • 4) • 10. V = 502.4 cm^3
