This question has two parts. Many artists incorporate geometric shapes into their art. An artist wants to make a sculpture shaped like a cone with a height of 4.2 inches and a radius of 2.5 inches. The artist needs to know the volume of the sculpture to purchase the correct amount of materials.

Part A. Which equation should the artist use to calculate the volume of the cone with the given measurements?

1. V=4/5π (2.5)³
2.V=π(2.5)²(4.2)
3.V=1/3 (2.5)² (4.2)
4.V=1/3π (2.5)²(4.2)

B. What is the Volume Of The Cone?
