Radius of Circle given Arc Length Formula. The area can be found by the formula A = r2. We know the slice is 60. If we are only given the diameter and not the radius we can enter that instead, though the radius is always half the diameter so its not too difficult to calculate. This special oval is formed by two circles with radiuses R and r and a distance a of their centers. With these measurements, you can use this calculator to compute the radius (r) of the circle that will be your guide. Our pie has a diameter of 16 inches, giving a radius of 8 inches. When two radii become collinear, that combined length is called the diameter of the Circle. To set out a large radius arc in a confined area, enter either the maximum height of the arc (above centre of chord), or the radius of the arc, and the increment along the chord line for your set out points. The length of the arc and the angle subtended Plugging our radius of 3 into the formula, we get C = 6 meters or approximately 18.8495559 m. Now we multiply that by \(\frac{1}{5}\)(or its decimal equivalent 0.2) to find our arc length, which is 3.769911 meters. So, our arc length will be one fifth of the total circumference. Do not mix inside, outside, and centerline dimensions). centimeters or yards) via the pull-down menu.
