So you have it right. 15 5/7 in

Explanation:

C = πd

All you can do now is substitute what has been given

Diameter = 5

Pi = \frac{22}{7}

7

22

C = \frac{22}{7}

7

22

* 5

Multiply from across

22 * 5 = 110 ( numerator)

7 * 1 = 7 (denominator)

110/7 (improper fraction) = 15.71428571428571 ( as a decimal) = 15 5/7 ( as a mixed number)

Ik its 15 5/7 because 1. the 15 wont change, and 2 5/7 = 0.7142857142857143, which is the same one as above

Hope this helped!

Answer:

All you can do now is substitute what has been given

Diameter = 5

Pi =
(22)/(7)

C =
(22)/(7) * 5

Multiply from across

22 * 5 = 110 ( numerator)

7 * 1 = 7 (denominator)

110/7 (improper fraction) = 15.71428571428571 ( as a decimal) = 15 5/7 ( as a mixed number)
