Radius of 90 inch circle
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 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.
