Question

If the circumstances of the circle below is 72, what is the length of AB (the minor arc)?

Answer 1

12

Explanation:

In the given circle circumference of the circle is = 72.

Since circumference of the circle = 2πr

`2\pi r=72`

`(2*22)/(7*r)=72`

`r=(72*7)/(44)=(504)/(44)=(252)/(22)=(126)/(11)=11.45`

`=\pi r \;theta /180=(22)/(7*11.45)*(60)/(180)`

`11.99=12(About)`

Thus, Answer = 12
