Question

1) Find the area of sector where radius 7cm
and angle = 120​

Answer 1

Answer :- 5.13cm²

solution:-

Radius = 7 cm.

= 7 cm. theta = 120 deg.

Area of sector = theta/360 × π × r^2.

Area of sector = theta/360 × π × r^2. = 120/360 × 22/7 × 7 × 7

= 22×7/3

= 154/3

so the area of sector is 5.13cm²

Answer 2

Answer:

sector area = theta/360*(πr^2)

=120/360*(π*7*7)

=1/3*22/7*7*7

=22*7/3

,=154/3
