WebFind the diameter of a circle if its radius is 3 cm. Solution: Given: Radius, R= 3 cm. We know that, if the radius is given, the formula to calculate the diameter is: D = 2R. Substitute R = 3 cm in the formula, we get. D = 2(3) D = 6 cm. Example 2: The circumference of a circle is 36 cm. Calculate the diameter of a circle. Solution: Given: 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 ...
