Answer:
Find the volume of the sphere.
Either enter an exact answer in terms of π or use 3.14 for π and round your final answer to the nearest hundredth.
The radius is 1
Volume =
or 4.19
Step-by-step explanation:
Given
Radius, r = 1
Required
Find the volume of sphere
Volume of a sphere is calculated using the following formula

Where V = Volume and r = radius
By Substitution,

Solving further to get the numerical value of volume;
We have to substitute 3.14 for π

V = 4.19 to the nearest hundredth
