Answer: The area (A) of a circle is a function of its radius (r) and is given by the function A = f(r) = πr2.
Step-by-step explanation: google help
The area is a function of the radius and the radius is a function of the area.
For a circle of radius R, we can write the area as:
A = pi*R^2
So we can write the area in terms of the radius, meaning that yes, the area is a function of the radius of a circle.
If we take the above equation and we isolate R, we get:
R = √(A/pi)
So you can also write the radius in terms of the area, meaning that the radius is also a function of the area.
