Question 1069884
A circular mirror is surrounded by a square metal frame.
 The radius of the mirror is 2x. The side length of the metal frame is 10x.
 What is the area of the metal frame 
Metal frame are = square area - mirror area 
A = {{{(10x)^2 - (pi*(2x)^2)}}}
A = 100x^2 - 12.566x^2
A = 87.434x^2 sq/units
