Janeka found the area of a circular side table with a diameter of 20 inches. Explain the error(s) that she made. Include the correct answer in your response.
A = π r² A = π (20 in)² A = 400 π in
She took the diameter.....she should have used the radius = 20 / 2 = 10 in
pi ( 10)^2 =
100 pi (in)^2 Also it needs to be (in)^2 instead of just inches
No prob !!!!
