WebSolution: We know that the central angle = 120 ∘, and the arc length is 8 inches. Using the formula, Central Angle = s × 360 2 π r. where, “ s ” is the length of the arc, and “ r ” is the radius of the circle. 120 ∘ = 8 × 360 2 π … WebThe circumference can be found by the formula C = πd when we know the diameter and C = 2πr when we know the radius, as we do here. Plugging our radius of 3 into the formula, we get C = 6π meters or approximately 18.8495559 m. Now we multiply that by (or its decimal equivalent 0.2) to find our arc length, which is 3.769911 meters.

WebThe central angle formula is calculated using the arc measure and inscribed angle of a circle. The angle measure of the central angle is congruent to the measure of the … WebThat is literally half of the circumference of the circle. That is half of the circumference, half of the way around of the circle, circumference of the circle. So this angle is going to be half of 360 degrees. And half of 360 is 180 degrees. And when you view it this way, these two rays share a common endpoint.

WebCentral Angle= s×3600 2πr s × 360 0 2 π r. Here "s" is the length of the arc and "r" is the radius of the circle. This is the formula for finding central angle in degrees.
