• A. 52 "]' style="font-size:13px;font-family:arial,sans,sans-serif;">
• B. 52 "]' style="font-size:13px;font-family:arial,sans,sans-serif;">

Answer 1

The correct option is B

52 "]' style="font-size:13px;font-family:arial,sans,sans-serif;">

Area of the sector of angle $\theta$ = $\frac{\theta }{360}$ × $\pi$ × ${10}^2$

= 52 $\frac{8}{21}$ $c{m}^2$
