Answer :
The area of ANYTHING circular is (pi) x (the circle's radius)².
Radius = 1/2 of the diameter
Radius of the mirror = 6 inches
Area of the mirror = (pi) x (6 inches)²
= (pi) x (36 inches²) = 113 square inches (rounded)
A= pi x r^2
r= d/2
A= 3.14 x 6 x 6
A=113,04
Area = 113 square inches
hope this helps
