Q. 11

# The area of a minor sector of a circle is 3.85 cm^{2} and the measure of its central angle is 36°. Find the radius of the circle.

Answer :

As we know that,

Given area of sector, A = 3.85 sq.cm

Radius of circle= r

Central angle, θ = 36°

On substituting the values, we get,

⇒ r = 3.5 cm

∴ Radius of circle is 3.5 cm
