Question

The circumference of a round mirror is 32 inches. What is the radius of the mirror?

Answer 1

The radius of the mirror is approximately 5.093 inches.

Step-by-step explanation:

To find the radius of the mirror, we need to use the formula for the circumference of a circle, which is C = 2πr, where C is the circumference and r is the radius.

In this case, we're given that the circumference is 32 inches, so we can plug in the values and solve for the radius:

C = 2πr

32 = 2πr

Divide both sides by 2π:

r = 32 / (2π)

Using a calculator to approximate π, we find that r ≈ 5.093 inches.

Answer 2

r=C/2pi

r= 32/2pi. pi=3.1415. 2pi= 2×3.1415 =6.2831

given that C= 32, therefore r=32/6.2831 =5.0930.
