Find the radian measure of the central angle of a circle of radius r = 4 inches that intercepts an arc length s = 20 inches.

The formula for an arc length is a = r?, where'd is the arc length, ? is the central angle in radians, and r is the radius. That said, s = 20, r = 4, and ? is unknown.

= 5 radians

The central angle is 5 radians.In which quadrant will the angle 100 degrees lie in the standard position?

The angle of 100 degrees will lie in Quadrant II.

In which quadrant will the angle -305 degrees lie in the standard position?

The angle of -305 degrees will lie in Quadrant I.

Find the length of the arc on a circle of radius r = 5 yards intercepted by a central angle 0 = 70 degrees.
