Answer 2

Answer:

Given: An arc subtends an angle of θ = 108° at the centre of a circle of radius r = 10 cm.

To find the area of the sector.

The area of the sector of a circle of radius r subtending an angle of θ is,

A

By substituting the given values in the above equation, we have

Further solving the above equation, we get

Therefore, the area of the sector formed by an arc subtending an angle of 108° at the centre of a circle of radius 10 cm is 30πcm2
