#### Question

The radius of a circle is 10 cm. The area of a sector of the sector is 100 cm2. Find the area of its corresponding major sector. ( $\pi$  = 3.14 ).

#### Solution

Radius of the circle, r = 10 cm
Area of the sector = 100 cm2

∴ Area of the corresponding major sector = Area of the circle − Area of the sector

$= \pi r^2 - 100$
$= 3 . 14 \times \left( 10 \right)^2 - 100$
$= 314 - 100$
$= 214 {cm}^2$

Thus, the area of the corresponding major sector is 214 cm2.

Is there an error in this question or solution?
