Answer:

The radius is approximately 8.5 units.

Step-by-step explanation:

C = 2πr

53.4 = 2(3.14)r                 multiply

53.4 = 6.28r                      divide both sides by 6.28

8.50 ≈ r

hope i helped :)

Answer:

2.5m

Step-by-step explanation:

C=2πr

We know the Circumference is 15.7, and are assuming pi as 3.14:

15.7=2(3.14)r

1) Simplify:

15.7=6.28r

2) Divide both sides by 6.28

r=2.5
