Question

The circumference of a circular painting is 40.82 feet. What is the radius of the painting? Use 3.14 for pie and do not round your answer.

Answer 1

The radius is equal to 6.5 feet.

Explanation:

To solve this we need to know that circumference equals 2πr (where "r" is the radius). Therefore, we can make the following equation...

2πr = 40.82

πr = 20.41

3.14r = 20.41

r = 6.5

Now we know that the radius is equal to 6.5 feet.
