Circumference knowing diameter
WebThe circumference is the distance around the circle. In other words, the circle's perimeter. The diameter is a straight line that passes through the center of the circle. The radius is half of the diameter. It starts from a point on the circle, and ends at the center of the circle.

WebNov 28, 2024 · Finding the Radius or Diameter of a Circle Given Area The formula for the area of a circle, A = πr2, can also be used to solve for the radius and diameter. Let’s look an example. The area of a circle is 113.04 square inches. What is its radius? First, write the formula. A = πr2 Next, substitute in what you know. 113.04 = (3.14)r2 WebCircumference is equal to 2 pi r. And in this case, r is equal to 6. So it's equal to 2 pi times 6, which is going to be equal to 12pi. So that's straightforward, area 36pi, we leverage pi r squared to figure out that the radius was 6, and then from that we were able to figure out that the circumference was 12pi. Up next: video
