#### Question

In the given figure, the radius of the circle is 7 cm and m ( arc MBN) = 60

^{°},find Area of the circle.

#### Solution

Radius of the circle, r = 7 cm

m(arc MBN) = ∠MON = θ = 60º

Area of the circle = \[\pi r^2 = \frac{22}{7} \times \left( 7 \right)^2\] = 154 cm^{2}

Area of the circle = 154 cm^{2}

Is there an error in this question or solution?
