Answer 1

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
