Question

What is the volume of a cone that has a circumference of 309 feet and a height of 18 feet

Answer 1

Answer:

v = 1.8 x 10^6

Step-by-step explanation:

v= π r 2h /3

Answer 2

Answer:

V = 45,235 ft³

Step-by-step explanation:

The general formula for the volume of a cone:

V = $\frac{1}{3}$πr³, where r = radius

Given the circumference of 309 feet, you can solve to find the radius of the cone:

C = 2πr or 309 = 2πr

Divide by 2π: 309/2π = 2πr/2π

Solve: r ≈ 49

V = $\frac{\pi r^{2}h}{3}=\frac{\pi 49^{2}}{3}=45,235$
