How do i figure out the radius of a circle
WebWe 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 WebRadius: the distance between any point on the circle and the center of the circle. It is equal to half the length of the diameter. Diameter: the largest distance between any two points …
