Question

The formula for the volume of a sphere is 4 ⁄ 3 πr^3
​3
​​ . The volume of a softball with a radius of 2 inches is about

Answer 1

Answer:

Volume of a sphere

= 4/3πr³

= 4/3*3.14*2*2*2

= 4/3*25.12

=33.493 inches³

Answer 2

The volume of a shape is the amount of space in it.

The volume of the softball is about 33.5 cubic inches

The volume of the sphere is given as:

$V = \frac 43\pi r^3$

The radius of the softball is given as:

$r = 2$

So, the volume of the softball is:

$V = \frac 43\pi \times 2^3$

$V = \frac 43\pi \times 8$

Express pi as 3.14

$V = \frac 43 \times 3.14 \times 8$

$V = 33.49$

Approximate

$V = 33.5$

Hence, the volume of the softball is about 33.5 cubic inches
