Sagot :

Answer:

#7 = 53.41

#8 = 18.85

#9 = 87. 96

Step-by-step explanation:

The formula for Circumfrance of a circle is: C=2 π r

So lets do #7:

17/2 (the radius is 1/2 of the diameter)

R= 8.5 (now plug in)

C= 2 π 8.5

C=17π

Now repeat on 8 and 9

8:

C= 2 π 3

C=6π

c= 18.85

9:

C= 2 π 14

C= 28π

C= 87.96
