Question

If you get how to do this could you please help me on this question?

Answer 1

Explanation:

area of the sector = 144 π

the whole circle is πr²= 36²π = 1,296π

the whole circle has an angle of 360°

the area of the sector has the angle ∠FAN

∠FAN/360 = 144π/1,296π

∠FAN = 360 * 144π/ 1,296π

∠FAN = 40°

Answer 2

fan is at 75 degree angle
