Answer: The volume of a sphere of radius 3cm is 113.143cm3. Note- In order to solve this question, we must know the formula of the volume of the sphere i.e. 43πr3.
The formula for the volume of a sphere is V = 4/3 π r³, where V = volume and r = radius.
For example: Because your formula tells you to cube the radius. Since the radius is in inches, then you also cube your inches. Thus your answer is 267.95 inches cubed. Now, if your radius was 4 feet instead of 4 inches, then your answer would be 267.95 feet cubed.
Final Answer = 113.143cm3.
