Question

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

Answer 1

Answer:

12

Step-by-step explanation:

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

Since circumference of the circle = 2πr

$2\pi r=72$

$\frac{2*22}{7*r}=72$

$r=\frac{72*7}{44}=\frac{504}{44}=\frac{252}{22}=\frac{126}{11}=11.45$

$=\pi r \;theta /180=\frac{22}{7*11.45}*\frac{60}{180}$

$11.99=12(About)$

Thus, Answer = 12
