Question

The radius of a circle is 2 feet. What is the area of a sector bounded by a 45° arc?

Answer 1

1.57 square feet

Explanation:

Given :-

Radius = 2 feet

θ = 45°

Formula to be used :-

Area (sector) = πr² x θ / 360°

Inputting the values :-

= 3.14 x (2)² x 45/360

= 3.14 x 4 x 1/8

= 3.14 x 1/2

= 1.57 square feet
