The radius of a sphere is 7 in. what is the sphere's volume? round to the nearest tenth, if necessary.

I believe the answer is:
1436.76in³ 

The volume of a sphere refers to the number of cubic units that will exactly fill a sphere. The volume of a sphere can be found or calculate by using the formula V=4/3πr^3, where r represents the radius of the figure.

In this exercise is given that the radius of a sphere is 7 inches and it is asked to find its volume. The first step to find the volume of the sphere will be the substitution of the given values into the previous mention formula.

V=4/3πr^3
V=4/3π(7)^3
V=4/3π(343)
V=457.33π in^3 or 1436.76 cubic inches

The volume of the sphere is 457.33π in^3 in terms of pi, or 1436.76 cubic inches.

Uh idk bossman just do it lol
