Question

An inflatable beach ball has a circumference of 141.3 centimeters what is the volume of the beach ball when fully inflated

Answer 1

The volume of fully inflated ball is 47688.75 cubic centimeter

Explanation:

Step 1 :

The circumference of the given beach ball = 141.3 centimeters

We need to find volume of the inflated ball

Step 2 :

Circumference = 2
`\pi` r = 141.3 [r is the radius]

=> r = 22.5 [ This is obtained by dividing 141.3 by 2
`\pi`]

The volume of the fully inflated ball is the volume of a sphere with the radius 22.5

Therefore volume = (4/3)
`\pi` r³ = (4/3)
`\pi` (22.5)³ = 47688.75 cubic centimeter

Step 3 :

Answer :

The volume of fully inflated ball is 47688.75 cubic centimeter
