A sector of a circle of radius 4 cm subtends an angle of 30°. Find the area of the sector.

Answer»

Given,

Radius = 4 cm

Angle subtended at the centre O = 30°

We know that,

Area of the sector = θ/360 ∗ πr²

= 30/360 ∗ π4² =1/12 ∗ π16 = 4π/3

Therefore, the area of the sector of the circle = 4π/3 cm²
