Question

A paper popcorn cone measures 4 inches in diameter and 9 inches high. What is the volume of popcorn that can be contained within this cone? Use 3.14 for pi. Round your answer to the nearest hundredth.

Answer 1

Let me restate the given:

Diameter = 4 inches
height = 9 inches

The volume of a cone is formulated as V = (πr²h)/ 3

Since the formula uses a radius and the given is the diameter of a circle, then simply divide the diameter by 2 to get the radius. 

r = 2 inches

Solve for volume of cone:

V = [ (3.14) (2)² (9) ] / 3
V = 37.7 in³

The answer is 37.70 in^3.
