How do we find the circumference
WebCircumference = π × Diameter Example: You walk around a circle which has a diameter of 100m, how far have you walked? Distance walked = Circumference = π × 100m WebJan 16, 2024 · Area of a circle using circumference If you have no idea what the radius or diameter is, but you know the circumference of the circle, C, you can still find the area. Area and circumference formula Circumference (the distance around the circle) is found with this formula: C=2\pi r C = 2πr
How do we find the circumference
Did you know?
WebFrom the diameter and the circumference, we can find the radius and then find the area of a circle. But these formulae provide the shortest method to find the area of a circle. Suppose a circle has a radius 'r' then the area of circle = πr 2 or πd 2 /4 in square units, where π = 22/7 or 3.14, and d is the 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. Hope this helps! 3 comments ( 25 votes) Upvote Downvote Flag more
