Area of B ½b h ½ 20m 14m 140m 2. Area of a circle diameter. If you know the radius of the circle and the height of the segment you can find the segment area from the formula below.
Area of a circle formula The formula for the area of a circle is p x radius2 but the diameter of the circle is d 2 x r 2 so another way to write it is p x diameter.
Diagram 1 Area of Circle. Area of the circle pi r2 Area of the circle frac227 x 492 considering pi frac227 frac227 x frac4910 x frac4910 7546 sq m. It can be determined easily using a formula A pr2 Pi r-squared where r is the. By using the surface area of a circle formula to find area find two times the radius and multiply the obtained value with pi constant 314 then again multiply the value you have got with 4.
