The radius of a circle has no bearing on the angular measure of the arc: the radius can have any positive value.
When the arc length is the same size as a circle's radius it is known as a radian and it measures just under 57.3 degrees

Not enough information is given to work out the radius of the circle as for instance what is the length of sector's arc in degrees
To find the arc length of a circle given a central angle, you can use the formula: Arc Length = (θ/360) × (2πr), where θ is the central angle in degrees and r is the radius of the circle. For a circle with a radius of 60 inches and a central angle of 35 degrees, the arc length would be: Arc Length = (35/360) × (2π × 60) ≈ 36.7 inches.

The radius of a circle is the length of the line from the center of the circle to any point on its edge.
A full circle measures 360 degrees, regardless of its size. If you meant a circle with a radius of 1 and a quarter (1.25), it still has 360 degrees. The number of degrees in a circle remains constant at 360, no matter the circle's dimensions.
The length of an arc measuring 60 degrees given a circle with a radius of 6 is 2*pi, that is 6,2831 approximately.The perimeter of a circle is calculated with the formula:L = 2 * pi * rwhere L is the perimeter and r the radius of the circle. This is equivalent to calculating the length of an arc measuring 360 degrees. The length of any arc smaller than 360 is proportionally smaller. Given that 60 degrees is 1/6 of the total circle (360), the length of the arc will be 1/6 of the perimeter.2 * pi * 6L = --------------- = 2 * pi6
It depends on what information you have: the radius and the area of the sector or the length of the arc.
Length of a radius is always half the diameter of a circle. This means that the circle has a radius of 2cm.
In order to answer that question, we'd need to see the drawing, and find out how 'ab' is related to the circle.
