The answer depends on what you want the formula for: the radius, circumference; the equation of the circle in some coordinate plane - and if so, in how many dimensional space?
Area formula for circle= --,,- r 2
It is 100*(Measured Value/True Value - 1)
The formula to find the area of a circle is pi x the radius squared.
There is no specific formula for a sector of a circle. There is a formula for its angle (at the centre), its perimeter, its area.
The formula for the area of a circle is: Area = (pi) x (Radius)2 . When you know the radius of the circle and you use it to calculate the area of the circle, the result will be equal to (pi) x (Radius)2 .
The formula for the area (A) of a circle is A = πr2. If the area is 100π then 100π = πr2 : 100 = r2 : r = √100 = 10. The radius is of length 10 units.
Area = Pi*r2 = Pi*502 = approximately 7,853.98 units2
the formula for the area of a circle is 3.14 x radius squared
The formula to find the area of a circle is: A = pi * r2
Use the standard formula to calculate the area of the circle, then you can compare with the area given for the triangle. Note 1: The formula for a circle is: area = pi x radius squared Note 2: The radius is half the diameter
The area of a circle can be found with the formula (pi)r^2
Area formula for circle= --,,- r 2
The formula for double the area of a circle
The formula to find the area of a circle is pi x the radius squared.
It is 100*(Measured Value/True Value - 1)
Area of a circle = pi*radius2
I suggest you use the standard formula for the area of a circle. Then, convert the area from square meters to hectares (1 ha = 10,000 m2).
