1 point A circular pool of oil grows so that the radius increases by 2 feet. The
formula A=Tt(r+2) can be used to determine the area of the circle. Amelia
wants to determine the radius of the original circle if she can determine the
approximate area covered in oil. She decided to complete the steps below
to solve her equation for the radius, r. Sonya is reviewing Amelia's work and
disagrees with Amelia. Identify Amelia's mistake, why this step will not
work, and then model the correct solution process for Amelia.*
Step 1: A = a(r + 2)2
Step 2: EVA = n(r + 2)
Step 3: +
=r + 2
T
VA
Step 4: -2+
=r
TT
