Formula: θ =s/r θ = measure of thecentral anglein radians s= arc length r= radius of the circle Example: s= 10 r= 5 θ = 10/5 = 2 radians Commonly used angles in degrees and radians See also Special angles
Formula for S=rθS=rθ The picture below illustrates the relationship between the radius, and the central angle in radians. The formula is S=rθS=rθ where s represents the arc length, S=rθS=rθ represents the central angle in radians and r is the length of the radius. Demonstrati...
13-3: Radian Measure Radian Measure There are 360º in a circle The circumference of a circle = 2r. So if the radius of a circle were 1, then there a. 13.3 Radian Measure A central angle of a circle is an angle with a vertex at the center of the circle. An intercepted arc...
Radian Measure is one of the units for measuring angles in mathematics. Click here to learn more about radian measure, how to calculate angle measurements in terms of radians.
Substituting C into the formula s = θr shows: C =θr 2πr = θr 2π = θ The arc measure of the central angle of an entire circle is 360º and the radian measure of the central angle of an entire circle = 2π. 360º (degrees) = 2π (radians) 360º = 2π (divide...

Ais a unit used to measure an angle, specifically the central angle of a circle. The concept of the radian is closely tied to the unit circle. Ais a circle with a radius of 1 unit. One radian is the measure of the central angle of a circle when the arc it forms on the circumferenc...
placed at thecenter of a circle,intercepts an arcequal in length to the radius of the circle. Note that 2π radians = 1 revolution = 360°and so π radians = 180°. Thus, 1 radian = 180°/π ≈ 57°. Very Important:When no unit of measure is indicated on an angle, the ...
