Question

Find the area of sector, whose radius is 7 cm with the 30 degrees angle?

Answer 1

Step-by-step explanation:

$Given: \\ \theta = 30 \degree \\ r = 7 \: cm \\ Area \: of \: sector: \\A = \frac{\theta}{360 \degree} \times \pi \: {r}^{2} \\ = \frac{30 \degree}{360 \degree} \times \ \frac{22}{7} \: \times {7}^{2} \\ = \frac{1}{12} \times 22 \times 7 \\ = \frac{77}{6} \\ = 12.83 \: {cm}^{2}$
