Question

Find the radius of a circle with a circumference of 36 Inches

Answer 1

Answer:

r≈5.73in

Step-by-step explanation:

Using the formula

C=2πr

Solving for r

$C=\frac{C}{2\pi } =\frac{36}{2}$·$\pi$  ≈5.72958in

Answer 2

Answer:

r = 18/pi

or approximately 5.7325 inches

Step-by-step explanation:

The circumference is given by

C = 2*pi*r

36 = 2*pi*r

Divide each side by 2 pi

36/(2pi) = r

18/pi = r

Letting pi = 3.14

18/3.14

5.732484076 = r
