WebApr 7, 2024 · You can find the measure of ∠AKB as follows: θ = ∠AKB = 180 - 117 = 63 degrees. Now that you know the value of θ and r, you can substitute those values into the Sector Area Formula and solve as follows: Replace θ with 63. Replace r with 5. r^2 equals 5^2 = 25 in this example. Simplify the numerator, then divide. WebAnswer (1 of 2): Lets assume the object is moving in a circle of radius R. Then the circumference (C) is.. C = 2*Pi*R The ark length is some fraction of the circumference… Arc length/(2*Pi*R) One full revolution is an angular displacement of 2*pi Radians. So to work out the angular displaceme...

WebThe length (more precisely, arc length) of an arc of a circle with radius r and subtending an angle θ (measured in radians) with the circle center — i.e., the central angle — is =. This is because =. Substituting in the circumference =, and, with α being the same angle measured in degrees, since θ = α / 180 π, the arc length equals =. A practical way to determine the … WebSection 4.2 – Radians, Arc Length, and the Area of a Sector 2 Example 1: A central angle, T = 2 S, in a circle intercepts an arc of length 5 12S m.
