Diameters in math
WebThe following video gives the definitions of a circle, a radius, a chord, a diameter, secant, secant line, tangent, congruent circles, concentric circles, and intersecting circles. A secant line intersects the circle in two points. A tangent is a line that intersects the circle at one point. A point of tangency is where a tangent line touches ... WebArea of a circle, A = 125 cm 2. If the circle’s area is given, then the formula to calculate the diameter of a circle is given by: D = 2 A π. Now, substitute the value of A and π in the formula, we get. D = 2 125 3.14. D= 2 (6.31) D = 12.62 (approximately) Thus, the diameter of a circle is 12.62 cm.
