Question

The area of a sector of a circle with radius 12 cm and angle 60° is .

• A. $34\pi c{m}^2$
• B. $24\pi c{m}^2$
• C. $26\pi c{m}^2$

Answer 1

The correct option is B $24\pi c{m}^2$

Radius of circle = 12 cm
$\theta =60°$
$\therefore \text{Area of sector}=\frac{\theta }{360°}\times \pi r^2$
$\frac{60°}{360°}\times \pi (12{)}^2=24\pi c{m}^2$
