To find the area of a circle you use the equation: A=pi*r2
So, you would find the area of the circular mirror by plugging in the numbers.
Area=3.14*(38)2
Area=4534.16 in2
A circle with a radius of 11 inches has an area of 380.13 square inches.
A circle with a radius of 18 inches has an area of 1,017.88 square inches.
The radius of a circle with an area of 706.50 square inches is: 15 inches.
A circle with a radius of 5.1 inches has an area of 81.71 square inches.
A circle with a radius of 3 inches has an area of 28.27 square inches.
Assuming it is a circular mirror, let the radius of the mirror be R inches. Then the combined radius is R + 3 inches → Combined area is π × (R + 3)² square inches. [If you know the radius of the mirror, substitute its value for R in the above formula and you will get the area in square inches. If the mirror is another shape, you'll have to reask your question with more information.]
