Question

The circle has a radius of 11 cm. What is the area of the shaded sector? Use 3.14 for π, and round your answer to the nearest tenth.

What is the approximate area of the shaded sector?
23.0 cm2
126.7 cm2
253.3 cm2
379.9 cm2

Answer 1

C. 253.3 cm2

Explanation:

Answer 2

C) 253. 3 cm²

Explanation:

1. Sector area formula can be in degrees or radians. I will use degrees because we are given 240 degrees as a unit.

2. SA=
`(x)/(360)` times
`\pi r^(2)` where x is the degrees of the sector

3. 240/360 times 3.14(11)²

4. 0.66666667 times 379.94

5. approximately 253. 3 cm²
