Answer:
r = 10
Step-by-step explanation:
C = 62.8 = 2π·r
62.8 = 2·3.14·r
r = 62.8/2·3.14
= 31.4/3.14
= 10
Answer:
10 miles
Step-by-step explanation:
The circumference of a circle can be found using:
[tex]c=2r\pi[/tex]
We know circumference is 62.8, so we can substitute it in
62.8=[tex]2r\pi[/tex]
We want to find r, so we have to isolate it.
Divide both sides by [tex]2\pi[/tex] or 2*3.14 which is 6.28
62.8=[tex]2r\pi[/tex]
62.8=6.28r
62.8/6.28=6.28r/6.28
r=10
So, the radius is 10 miles
