Problem

Find the area of a sector of a circle with a central angle of 60 degrees and a radius of 8 ft.

Step

The given values are

angle = 60 and r = 8 ft

Formula

The area of a sector of a circle

\$ A = (θ/360) \times π \times r^2\$

Step

Substitute the values

\$A = 60/360 \times 3.141 \times (8)^2\$

Step

After simplification

\$ A = 1/6 \times π \times 64\$

Step

After simplification

A = 33.51 sq.ft

Step

The area of a sector of a circle 33.51 sq.ft
