Question

What is the approximate volume of a baseball with a radius of 1.5 inches?

A.
7.1 cubic inches

B.
9.4 cubic inches

C.
10.6 cubic inches

D.
14.1 cubic inches

Answer 1

14.13

Explanation:

Sphere formula;

v = 4/3πr^3

Where pi is 3.14 or 22/7

R is the radius which is cubed

Substitute the radius(1.5) into the formula:

v = 4/3πr^3

v = 4/3 * 3.14 * 1.5^3

v = 4/3 * 3.14 * 3.375

v = 4/3 * 10.5975

v = 42.39/3

v = 14.13, our closest answer would be D.

Answer 2

Answer: D. 14.1 cubic inches

Explanation:

Formula for volume of a sphere: 4/3 x pi x radius cubed

Substitute: 4/3 x pi x 1.5 cubed

= 14.1
