Answer:
18.84 feet
Step-by-step explanation:
The circumference of a circle can be found using:
c=π*d
The radius is given, but we have to find diameter. The diameter is twice the radius, or
d=2r
The radius is 3 feet. Substitute 3 in for r.
d=2*3
d=6
The diameter is 6 feet.
Now we have the diameter. We can substitute 6 in for d in the circumference formula. We can also substitute 3.14 in for pi.
c=3.14*6
c=18.84
The circumference is <u>18.84 feet</u>
18.85ft
4.47100222
157/2.5=62.8
62.8/pi= 19.98986085
square root the answer above and you get 4.47100222 for the radius
16 - 12 + 60 = 9
