To define our trigonometric functions, we begin by drawing a unit circle, a circle centered at the origin with radius 1, as shown in Figure 2. The angle (in radians) that t. t. intercepts forms an arc of length s. s. . Using the formula s = rt. s = r t. How Many Radians Are in a Circle? The number of radians in a circle is equal to 2 pi, or approximately 6.28. Since there are 360 degrees in a circle, each radian is equal to 360 divided by 6.28, approximately 57.3 degrees. A radian is the measure of the central angle of a circle that forms an arc equal in length to the radius of the circle. The value of tan 11pi6 can be calculated by constructing an angle of 11π6 radians with the x-axis and then finding the coordinates of the corresponding point 0866 -05 on the unit circle. 23π 6 - 23 π 6. Tap for more steps. Where in our case is the terminal side of the angle in standard position. The general equation of a circle is (x – a) 2 + (y – b) 2 = r 2, which describes a circle having the center (a, b) and the radius r. This equation can be simplified to represent the equation of a unit circle. A unit circle is made with its center at the point (0, 0), which is the origin of the coordinate axes. and a radius of 1 unit. She notices that the 6-inch-long minute hand is rotating around the clock and marking off time like degrees on a unit circle. Part 1: How many radians does the minute hand move from 1:20 to 1:55? (Hint: Find the number of degrees per minute first.) Part 2: How far does the tip of the minute hand travel during that time? n a unit circle. 500 Rotations = 3141.59 Radians. 500000 Rotations = 3141592.65 Radians. 9 Rotations = 56.5487 Radians. 1000 Rotations = 6283.19 Radians. 1000000 Rotations = 6283185.31 Radians.
