It depends on what information you have.
pi(r2) = forumla for the area of a circle
1/2(bh)
I think the forumla is L=25*.95106(72/2)*2

Area of a circle = pi*radius2
Area of a circle = Pi * radius2
Area of a circle = pi*radius2
If the area of one circle is twice that of another, the ratio of the area of the smaller circle to the larger circle is 1:2. To express this as a percentage, the area of the smaller circle is 50% of the area of the larger circle. Thus, the ratio in percent of the smaller circle to the larger circle is 50%.
The area of a circle is the amount of space inside the circle. The area of a circle is calculated by multiplying pi(3.14159) by the radius squared.
Area of a circle is calculated by A=2*p*r where A represents the circle's area and r is the radius of the circle.
