WebJul 3, 2024 · Sector Angle = Arc Length * 360 degrees / 2π * Radius. The 360 represents the 360 degrees in a circle. Using the arc length of 3 inches from the previous slide, and a radius of 4.5 inches from slide No. 2, you would have: Sector Angle = 3 inches x 360 degrees / 2(3.14) * 4.5 inches Sector Angle = 960 / 28.26 WebFeb 3, 2024 · To calculate the radius of a circle by using the circumference, take the circumference of the circle and divide it by 2 times π. For a circle with a circumference of …

WebWe obviously can’t work with inches and centimeters in the same equation, so the easiest thing to do is convert the circumference from inches to centimeters. The conversion factor is 2.54 cm/inch. If we multiply 7.85 inches x 2.54 cm/inch, we’ll get 19.94 cm, because the inch units in both the numerator and denominator cancel out. WebDefinition: The radius of an arc or segment is the radius of the circle of which it is a part. A formula and calculator are provided below for the radius given the width and height of the … WebFor a circle of 8 meters, find the arc length with the central angle of 70 degrees. Solution: Step 1: Write the given data. Radius (r) = 8m Angle (θ) = 70 o Step 2: Put the values in the formula. Since the angle is in degrees, we will use the degree arc length formula. L = θ/180 * rπ L = 70 / 180 * (8)π L = 0.3889 * (8)π L = 3.111 * π scale solutions port elizabeth
