Question

The circumference of a circle is approximately 37.7 centimeters. Enter the radius of the circle, in centimeters. Round your answer to the nearest whole number.

Answer 1

37.7 = 2 x pi x r
18.85 = pi x r
r = 18.85/pi
or
r = 6

Hope this helps

Answer 2

The circumference of the circle is given as 2
`\pi`r where
`\pi` is a constant whose value is equal to 22/7 and r is the radius of the circle

From the given problem, we have the circumference =37.7

2
`\pi`r = 37.7

2*22/7*r = 37.7

r = 37.7*7/(22*2)

r = 263.9/44

r = 5.99

r = 6cm

Radius = 6 centimeters (Rounded to nearest whole number)
