Question

Radius of a sector of a circle is 3.5 cm and length of its arc is 2.2 cm. Find the area of the sector.

Answer 1

Given: Radius (r) = 3.5 cm,

length of arc (l) = 2.2 cm 

To find: Area of the sector. 

Area of sector = (l x r)/2

= (2.2 x 3.5)/2

= 1.1 × 3.5 = 3.85 cm² 

∴ The area of the sector is 3.85 cm².
