in may , the groundskeeper at spring lake golf club built a circular green with an area of 90 π square feet . in august , the groundskeeper doubled the distance from the center of the green to the edge of the green . what is the total area of the renovated green ?
"area = π r ^ 2 , so doubling the radius results in an area that is 4 times the original area . 4 ( 90 π ) = 360 π the answer is a ."
multiply(power(multiply(sqrt(90), const_2), const_2), const_pi)
