Question

find the area of sector whose radius is 7cm with an angle is 120°?
​

Answer 1

Radius = 7 cm. theta = 120 deg. Area of sector = theta/360 × pi × r^2. = 120/360 × 22/7 × 7 × 7.

Step-by-step explanation:

154/3

51.33

Answer 2

$\huge \boxed{ \fcolorbox{cyan}{white}{Answer : }}$

$\bf \underline \red{area \: of \: sector}$

Area of sector

$\frac{120}{360} \times \frac{22}{7} \times 7 \times 7$

$\frac{1}{3} \times 22 \times 7$

$\frac{154}{3}$

$= 51.3$

area of sector whose radius is 7cm is 51.3 sq. cm
