Find the diameter who circumference is 62.8 feet use 3.14 for pie a) 18 b) 22 c) 20 d) 21

c) 20

Step-by-step explanation:

The circumference is given by

C= pi *d

Substitute in what we know

62.8 = 3.14*d

Divide by 3.14

62.8/3.14 =3.14d/3.14

20 =d

exa:

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
