# find the length of the arc on a circle of radius r intercepted by a central angle θ

How many pizza slices with a central angle of 1 radian could you cut from a circular pizza? Have you ever wondered how to find the central angle of a circle? The length of an arc is directly proportional to the circumference of the circle and is dependent on both the central angle and the radius of the circle.

Join Yahoo Answers and get 100 points today. So if you need to find the length of an arc, you need to figure out what part of the whole … with r representing the radius. Since the problem defines L = r, and we know that 1 radian is defined as the central angle when L = r, we can see that the central angle is 1 radian. The radius is 10, which is r. The figure shows what this arc looks like. nobodyinterestingnobodyinteresting. a. parking is not free on Sunday but the store is open o This time, you must solve for theta (the formula is s = rθ when dealing with radians): Plug in what you know to the radian formula. c. Parking is free and the store is open on Saturday. The measure of an arc as an angle is the same as the central angle that intercepts it. If you think back to geometry, you may remember that the formula for the circumference of a circle is . You use the following formula to calculate the arc length: The symbol theta (θ) represents the measure of the angle in degrees, and s represents arc length, as shown in the figure: Time for an example. Use the formula for S = r Θ and calculate the solution. There is a formula that relates the arc length of a circle of radius, r, to the central angle, $$\theta$$ in radians. Pramod Kumar. Convert into radian measure. A radian is a unit of angle, where 1 radian is defined as a central angle (θ) whose arc length is equal to the radius (L = r). What patterns do you notice in 3, 8, 15, 24, 35, 48? The formula is $$S = r \theta$$ where s represents the arc length, $$S = r \theta$$ represents the central angle in radians and r is the length of the radius.
