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

 

So

 

pi  ( 10)^2   =   

 

100 pi   (in)^2         Also  it needs to be (in)^2   instead of just  inches
