Question

a beach ball has a diameter of 18 inches. what is the approximate volume, rounded to the nearest whole number, of the Inflated beach ball? Use 3.14 for pie A.) 24,417 in cube B.) 1,017 in cube C.) 9,156 in cube D.) 3,052 in cube

Answer 1

Hello!

A beach ball is in the shape of a sphere

To find the volume of a sphere you use the equation

$V = \frac{4}{3} \pi r^{3}$

V is volume
r is radius

Put in the values you know and 3.14 for pi

$V = \frac{4}{3} * 3.14 * 18^{3}$

Cube 18

$V = \frac{4}{3} * 3.14*5832$

Multiply

V = 24416.64

Round to the nearest whole number

V = 24417

The answer is A)24,417

Hope this helps!
