Question

The largest ball of yarn ever created has a radius of 6 feet. It took 30 years to create

Which formula could you use to determine the volume of the ball of yarn?
A. V = Bh

Β. V = 4pi * r ^ 2

C. V = 4/(3r ^ 3)

D. V = 4/3 * pi * r ^ 3


Using 3.14 for Pi which choice is the volume of the ball of yarn? (nearest hundredth)

A. 87.85 cubic feet

B. 150.72 cubic feet

C. 834.68 square feet

D. 904.32 cubic feet

Answer 1

D. V = 4/3 * pi * r ^ 3

V = 4/3 * 3.14 * 6^3
V = 4/3 * 3.14 * 216
V = 4.19 * 216
V = 904.32 cubic feet

Therefore, the volume of the ball of yarn is approximately 904.32 cubic feet.
