The function A (r)=ar2 gives the area of a circular object with respect to its radius r. Enter the inverse function r(A) to find the radius r required for area of A . Then estimate the radius of an
circular object that has an area of 80 cm2.
The inverse function is r(A) =
The radius of a circular object rounded to the nearest tenth is r (80) –
cm?
