22. The circumference of the circle below is

malfutka [58]

Answer:

The length of arc of circle with interior angle 60° is 18 meter

Step-by-step explanation:

Given as :

The circumference of circle = C = 108 meters

The interior angle at center of circle = 60°

Let The length of arc = L

So ,

Length of arc = L = $\frac{\Pi \times radius\times \Theta }{180^{\circ}}$

∵ circumference of circle = $2\times \Pi \times radius$

Or, 108 = $2\times \Pi \times radius$

∴ r = $\frac{108}{2\pi }$

So, Length of arc = $(\frac{\Pi \times \Theta }{180}) \times (\frac{108}{2\times \Pi })$

Or, L = $(\frac{\Pi \times \60 }{180}) \times (\frac{108}{2\times \Pi })$

Or, L = $\frac{36}{2}$ = 18 m

Hence The length of arc of circle with interior angle 60° is 18 meter Answer
