Question

Find the approximate radius a circle if its circumference is 37.68 inches. Use (pie symbol)= 3.14.

Answer 1

Circumference of a circle:
C = 2 pi r
r = C / 2 pi
r = 37.68 / (2 * 314)
r = 6

Area of a circle:
A = pi r^2
A = 3.14 * 6^2
A = 113.04

Answer:
The area of the circle is 113.04 square units

Answer 2

radius = 6 inches

Explanation:

37.68/3.14 = 12 = diameter

radius = 12/2 = 6 inches
