If a circle has radius r, then the area of the circle is pi r2, pi being about 3.14159.
I beleive the function you are looking for is A(c)=c/2*r
The area of a circle of radius 21 is 1386
Area of a circle = pi*radius squared
The area of a circle with a radius of 14.4 is 651.4
A circle with a radius of 135 units has an area of 57,255.53 square units.
If the area of a circle is 40.7 the radius is: about 3.6 (3.599)
You can certainly express the radius as a function of its area, yes. If the area is known, you can solve the formula for the area of the circle to uniquely get the radius. (The quadratic equation has two solutions; you will of course choose the positive solution for the radius.)
A = (pi)r2 A/pi = r2 √(A/pi) = r
A circle with a radius of 6 units has an area of 113.1 square units.
The area of a circle is defined as pir^2. The radius here is 4.9 cm, so pi4.9^2=24.01 pi. If you were to express it in terms of a number, it would be about 75.43.
The area of a circle if the radius is 9m 254.5m2
The radius of a circle with the area of 36 is 3.385
The area of a circle of radius 21 is 1386
Area of a circle = pi*radius squared
The area of a circle with a radius of 14.4 is 651.4
A circle with a radius of 135 units has an area of 57,255.53 square units.
A circle with a radius of 10m has an area of 314.16 m2
The area of a circle with a radius of 2m is: 12.566 m2
