Answer 1

Hello friends

____________________________

Given;

Angle (a) = 45°

Radius (r) = 14 cm

We know that,

Area of sector=

$\frac{a}{360} \times \pi \: r {}^{2}$

By putting the values we get,

Area of sector =

$\frac{45}{360} \times \frac{22}{7} \times 14 \times 14 \\ \\ = \frac{1}{8} \times \frac{22}{7} \times 14 \times 14 \\ \\ = \frac{1}{4} \times 11 \times 2 \times 4 \\ \\ = 11 \times 7 \\ \\ = 77sq.cm$
Therefore,

The area of sector = 77 sq.cm

I hope this will helps you......

Thanks.....
