Question

The circumference of a circular garden is 141 feet. What is the radius of the garden?

Round your answer to the nearest hundredth.

Answer 1

Explanation:

plug it in

circumference = 2 x Pi x r

141 = 2 x 3.14 x r

141 = 6.28 x r

141 ÷ 6.28 = r

22.45 = r

Answer 2

r ≈ 22.44 ft

Explanation:

The circumference (C) of a circle is calculated as

C = 2πr ( r is the radius ), then

141 = 2πr ( divide both sides by 2π )

`(141)/(2\pi )` = r , that is

r ≈ 22.44 ft ( to the nearest hundredth )
