Question

A circular mirror is surrounded by a square metal frame. The radius of the mirror is 5x. The side length of the metal frame is 15x. What is the area of the metal frame? Write your answer in factored form.

Answer 1

Area of circular mirror = pi(5x)^2
Area of square =(15x)^2

Area of metal frame = (15x)^2 - pi(5x)^2
