Comparing area of circular culvert vs area of rectangular box culvert, and provide a printout to concerned landowner. 9 2020/08/06 23:23 Female / Under 20 years old / Elementary school/ Junior high-school student / - /. Note: The result of the cos-1 function in the formula is in radians. Another method If you know the central angle of the segment (the angle subtended by the segment at the center of the circle) you can use the method Area of a circular segment given the central angle. Explore the formula for the area of a circle, by cutting it into sectors and rearranging the sectors to form a figure close to a parallelogram. Area = π. (Diameter / 2)2 Diameter of a Circle The diameter of a circle is the distance from one edge to the other, passing through the center. It is twice the radius. A circle circumference and radius are proportional. The area enclosed and the square of its radius are proportional. The constants of proportionality are 2 π and π respectively. The circle that is centred at the origin with radius 1 is called the unit circle. Thought of as a great circle of the unit sphere, it becomes the Riemannian circle.
This will calculate the area of a circle based on its diameter. Confused as to what diameter means? Scroll down for a diagram.

Area of a Circle Formula
The area of a circle is pi times the square of its radius. The radius is half the diameter.
Area = π * (Diameter / 2)2
