Step 1 The area A of a circle can be found using the formula A = 7², where r is the length of the radius of the circle. Recall that is an irrational number, but can be approximated as follows. Substitute A = 7²²² A 3.14 7= 3.14 for 7 and Submit Skip (you cannot come back) Need Help? Read It for r into the formula A = 7².
