Answer 2

Concept:

Given: Here is a response

A = π r² A = π (20 in)² A = 400 π

Find: find the  error that she made.

Solution: Diameter of the circular table=20 inches

radius of the circular table=

                                         = 10 inches

Area of the circular table= π

                                       = ×10×10

                                       =314.28  

Final answer: Her mistake was she can't convert the diameter into radius.
