Question

Illustrations:1
The area of a certain sector of a circle is 10 sq. units. If the radius of the circle be 3 units, find the angle of the
sector.​

Answer 1

Answer:

angle of sector=127.27°

Step-by-step explanation:

The area of a certain sector of a circle= 10 sq

the radius of the circle = 3 units

Area of sector =angle/360°×πr^2

10=angle/360°×22/7×3×3 (10×360×7)/(22×3×3)=angle

25200/198=angle

127.27=angle

Thus angle of sector=127.27°
