Step-by-step explanation:
Given Joan incorrectly finds the volume of a sphere with a diameter of 9 cm to be 9,156.24 cm^3. Her work is shown. Find and correct Joan’s mistakes. Then, find the correct volume of the sphere. Use 3.14 for pi. ( please write in a a paragraph/replying type form)
- Given Joan does a mistake while finding the volume of a sphere. So we need to find the volume of a sphere.
- Volume of a sphere is given by V = 4/3 π r^3
- So radius = diameter / 2
- = 9/2
- So we get
- V = 4/3 x 3.14 x 9/2 x 9/2 x 9/2
- V = 1526.04 / 4
- V = 381.51 cm^3
