Circular length
WebGiven a circle with radius, r, centered at point (h, k), we can use the distance formula to find that: where (x, y) is any point on the circle. Squaring both sides of the equation, we get the equation of the circle: (x - h) 2 + (y - k) 2 = r 2. Notice that if the circle is centered at the origin, (0, 0), then both h and k in the equation above ... WebThe length of an arc formed by 60° of a circle of radius “r” is 8.37 cm.
