Question

The diameter of a softball is 3.8 inches. Estimate the volume within the softball. Round answers to the nearest whole number and leave in the answer.

Answer 1

Answer: 29 cubic inches.

Explanation:

Given: Diameter of softball = 3.8 inches

Then radius of softball =
`(3.8)/(2)=1.9\ \text{inches}`

The volume of a sphere is given by :-

`V=(4)/(3)\pi r^3`, where r is the radius of sphere.

Then , the volume of the softball will be :

`V=(4)/(3)(3.14) (1.9)^3\Rightarrow\ V=28.7163466667\approx29\ ft.^3`

Hence, the volume of a softball =29 cubic inches.

Answer 2

24 cubic inches

Explanation:

We are to find the volume of a sphere so we will use the following formula:

`V=(4)/(3) \pi r^3`

where
`V` = volume of the softball and
`r` = the radius of the softball.

We know that the diameter of the softball is 3.8 inches so its radius will be
`(3.8)/(2) = 1.9` inches.

Putting this value of radius on the formula to get:

`V=(4)/(3) \pi r^3`

`V=(4)/(3) \pi 1.8^3`

`V=24.4`

Therefore, the volume of the softball to the nearest whole number is 24 cubic inches.
