Enter the height and length of the given arc in the below arc length calculator . The Radius of an Arch calculator computes the radius (r) of a circle that would trace an arc of a certain chord length (c) and at a certain height (h). So to find the sector area, we need to, First, lets find the fraction of the circles area our sector takes up. If the angle of the arc is , then you can relate /2 with R and B by the equation. Hence, the length of the arc if the radius of an arc is 8 cm and the central angle is 40 = 5.582 cm. A formula and calculator are provided below for the radius given the width and height of the arc. find arc length without the central angle. Then we just multiply them together.
Lets try an example where our central angle is 72 and our radius is 3 meters. Radius of Circle given Arc Length formula is defined as the length of any line from the center to any point on the Circle and calculated using the arc length of the Circle at a particular central angle and is represented as.
