Question

Find the area of the sector of a circle of radius 18 cm with central angle 35°

Answer 1

Solution :

radius of the sector ( r ) = 18cm

Central angle ( x ) = 35°

Area of the sector ( A ) = ( x/360 )× πr²

= ( 35/360 ) × ( 22/7 ) × 18²

= 99 cm²

Therefore ,

Area of the sector ( A ) = 99 cm²

Answer 2

Answer:

99 cm²

Step-by-step explanation:

Find the area of the circle:

Area = πr²

Area = π(18)² = 324π cm²

Find the area of the sector:

Area of the sector =  θ/360 x Area of circle

Area of the sector = 35/360 x 324π

Area of the sector = 99 cm²

Answer: The area of the sector is 99 cm²
