Question

heena wants to measure the volume of a ball that is 24 cm across. How should she set up her equation? v = one-third pi 24 squared (12). v = one-third p 12 squared (24). v = four-thirds pi 24 cubed. v = four-thirds pi 12 cubed.

Answer 1

Answer:

v = four-thirds pi 12 cubed.

Explanation:

A ball has a spherical shape. The volume of a spherical shape can be calculated using the following formula:

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

where,

V = Volume of Ball = ?

d = diameter of the ball = length across the ball = 24 cm

r = radius of ball = d/2 = 24 cm/2 = 12 cm

Therefore,

$V = \frac{4}{3}\pi (12)^3$

Hence, the correct answer is:

v = four-thirds pi 12 cubed.
