Question

area of a circle whose radius 25. and angle is 160° . find the length ​

Answer 1

Radius of circle = 25 cm

Angle of the arc = 160°

$\text{Length of arc of circle = } \frac{160\pi}{180} \times 25 \\ \\ \to \: \: \: \: \frac{ 8 \times 22 }{9 \times 7} \times 25 \\ \\ \to \: \: \: \: \frac{4400}{63} \\ \\ \to \: \tt \: \: \: \:69.84 \: \: m$
