Question

Find the radius of a circle with a circumference of 49 yards

Answer 1

7.8025

Explanation:

You get the circumfence formula 2 * pi * r

since you are looking for the radius divide 49/2 then the answer you get divide it by pi and then you have your radius

Answer 2

[I'm using 22/7 as pi in this question, for the sake of convenience, since the value of pi to be used isn't given.]

Circumference =
`2\pi r`

49 = 2 x
`(22)/(7)` x r

r = 49 x
`(7)/(44)`

r = approx. 7.8 yards
