Question

When calculating arc length or sector area, the angle must be measured in

radians

degrees

minutes

seconds

Expert Solution
Step 1

In the given question,

Area of sector is determined as , A.

A=12r2

Here, r is the radius of the circle and  is the angle in radians subtended by the arc at the centre of the circle.

This is the area of sector for the circle with radius of the circle r and angle .

It means the angle is measured in radians  where one radian is equal to the angle formed when the arc opposite the angle is equal to the radius of the circle.
