Question

Find area of segment Q=30°, r=7cm ​

Answer 1

Steps :

1. find the area of the whole sector
2. find the area of the triangle within the sector
3. subtract the area of the triangle from the area of the sector

Answer :

$\text{Area of sector =}~\frac{30}{360} \times \pi \times {7}^{2}$

$\text{Area of triangle =}~\frac{1}{2} \times {7} \times {7} \times \text{sin 30}$

$\text{Area of segment = Area of sector - Area of triangle}$
