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!
Have a supercalifragilisticexpialidocious day!
