Round to the nearest hundredth, if necessary.
Hint: C = πd
Enter

Answer 1

C=62.8

Explanation:

1) In the formula C=πd, d represents the diameter, which is 20 inches. All you need to do is apply 20 into the equation and you get C=π20.

2) They said to use 3.14 instead of pi, so we are going to multiply 20*3.14, which is 62.8.
