WebAs established, the only two measurements needed to calculate the area of a sector are its angle and radius. For example, if the angle is 45° and the radius 10 inches, the area is (45 / 360) x 3.14159 x 10 2 = 0.125 x … WebThe formula for the radius of a circle is: Radius = (Area / 3.14)2. The formula for radius can be carried out by taking the area of the circle and dividing it by pi (3.14) and then getting the square root.

Circular Cylinder Calculator

Web3. We know that the arclength s between the two points is given by s = 2 π r / x, where x is known. So, we know the angle α of the arc between the two points -- it's just α = s / r = 2 π / x. Then, using the formula from the first answer, we have: r sin ( α 2) = a 2. and so. r = 1 2 a sin 1 2 α = 1 2 a c o s e c 1 2 α. Or, in summary.
