How do i find out the diameter of a circle
WebGiven the radius of a circle calculate the area, circumference and diameter. Putting A, C and d in terms of r the equations are: A = π r 2. C = 2 π r. d = 2 r. Calculate r, C and d Given A. Given the area of a circle calculate the … WebWell, from the area, we could figure out what the radius is, and then from that radius, we can figure out what its circumference is. So we know that the area, which is 36pi, is equal to pi r squared. And so if you look at it on both sides of this equation, if we divide-- let me rewrite it so it's a little bit clearer in a different color.
