Question

What is the area of a circular sector determined by a central angle of 67° in a circle of radius 19.8 ft?
a. 229.22 ft²
b. 13,133.34 ft²
c. 84.3196 ft²
d. 115.3264 ft²

Answer 1

The entire circle is 360 degrees. We are talking about 67 degrees. So we need this fraction of the entire circle: 67/360. The area of the whole circle is pi (19.8)^2

Answer 2

Would it be a?

Answer 3

That's what I got.

Answer 4

67/360 = S / ( pi*(19.8)^2) where S is the area of the sector.
