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:

24 cubic inches

Step-by-step explanation:

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

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

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 $\frac{3.8}{2} = 1.9$ inches.

Putting this value of radius on the formula to get:

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

$V=\frac{4}{3} \pi 1.8^3$

$V=24.4$

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

Answer 2

Answer: 29 cubic  inches.

Step-by-step explanation:

Given: Diameter of softball = 3.8 inches

Then  radius of softball = $\dfrac{3.8}{2}=1.9\ \text{inches}$

The volume of a sphere is given by :-

$V=\dfrac{4}{3}\pi r^3$, where r is the radius of sphere.

Then , the volume of the softball will be :

$V=\dfrac{4}{3}(3.14) (1.9)^3\Rightarrow\ V=28.7163466667\approx29\ ft.^3$

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