Question

The circumference of a circle is 15 ft. What is the length of the radius? Use 3.14 for π. Round your answer to the nearest tenth of a foot.

Answer 1

Answer:

The radius of the circle is 2.4ft

Step-by-step explanation:

circumference of circle = 2πr

circumference = 15ft

2πr = 15

(2×3.14)r = 15

6.28r = 15

r = 2.4ft (near. tenth)

Answer 2

Answer:

The answer is 2.4 ft.

Step-by-step explanation:

C= 2πr

15= 2(3.14)r

15= 6.28r

15÷6.28= 6.28r÷ 6.28

2.4= r
