Question

The radius of a circle is 10 feet. What is the area of a sector bounded by a 45° arc?

Answer 1

39.25 square ft

Explanation:

`Area \: of \: sector = (45 \degree)/(360 \degree) * \pi {r}^(2) \\ \\ = (1)/(8) * 3.14 * {10}^(2) \\ \\ = (3.14 * 100)/(8) \\ \\ = (314)/(8) \\ \\ = 39.25 \: {ft}^(2)`

Answer 2

45°
r=10 m
