Question

When the degree measure of the angle at the center is 1, what is the area of the sector with radius r = 1?

• A.
• B.
• C. 360
• D. 180

Answer 1

The correct option is A

When degree measure of the angle at the center is $1^{\circ }$.

area of the sector = Area of the circle = $\frac{1}{360}$ × $\pi$

=$\frac{\pi }{360}$
