Question

A cone has a radius of 3 units and a height of 4 units.

1. What is this volume of this cone?

2. Another cone has quadruple the radius, and the same height. How many times larger is the new cone’s volume?

Answer 1

1. V = 37.7

2. V =603.19

Explanation:

1. V = (3.14)×3^2 4/3

V =37.7

2. V=(3.14)×(3×4)^2 4/3

V = (3.14)×12^2 4/3

V = 603.19
