Question

The radius of a circle is 4 feet. What is the area of a sector bounded by a 45 degree arc

Answer 1

2π ft²

Explanation:

Circle Area:

A = πr²

A = π × (4 ft)²

A = 16π ft²

Sector Area:

A = (45°)/(360°) × 16π ft²

A = 2π ft²

Answer 2

45/360 * 4^2 pi = 6.283
ANSWER IS 6.283 (3 decimal places)
