Question

Chris used 43.96 feet of fencing to enclose a circular garden. What is the radius, in feet, of the garden?

Answer 1

r = 7 ft

Explanation:

The circumference (C) of a circle is calculated as

C = 2πr ( r is the radius )

Here C = 43.96 , then

2πr = 43.96 ( divide both sides by 2 × 3.14 ← for π )

r =
`(43.96)/(2(3.14))` =
`(43.96)/(6.28)` = 7 ft
