Is radius a function of the area? Type yes or no.

Answer 1

Yes it is. No it is not.

Answer 2

Area is a function of the radius, but radius is not a function of the area

Explanation:

Since the area of a circle is
`A=\pi r^2`, the value of the area depends on the radius, so area is a function of the radius, but not the other way around.
