# The measure of an arc of a circle is 80° cm and its radius is 18 cm. Find the length of the arc. ( π = 3.14 ) - Geometry

ConceptLength of an Arc

#### Question

The 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.

#### Solution

Radius of the sector, r = 3.5 cm
Length of the arc, l = 2.2 cm
∴ Area of the sector = $\frac{1}{2}lr = \frac{1}{2} \times 2 . 2 \times 3 . 5$ = 3.85 cm

Thus, the area of the sector is 3.85 cm2.
