Question

30^{°} is the angle of a sector of a circle of radius r, then area of the sector is(1) πr^{2}/6 (2) πr^{2}/3 (3) πr^{2}/12 (4) πr^{2}/4 `​

Answer 1

Answer:

Angle of sector = 30°

Area of sector = Ф/360° πr^2

                        = 30°/360° πr^2

                        = 1/6 πr^2

                        = πr^2/6

So, the answer is (1) πr^2/6.

Hope you like the answer.

Answer 2

Answer:

(3) pie r^2/12

Step-by-step explanation:

area of sector =Q/360 ×pie × r^2

= 30/360×pie×r^2

= pier^2/12
