It depends on what r is and on what information you have.
Even if r is a radius of a circular shape, you would have different formulae depending on whether:
it is a sphere and you have the volume,
it is a sphere and you have the surface area,
it is a circle and you have the area,
it is a circle and you have the circumference,
it is a circle and you have the length and angle of an arc,
it is a cone and you have volume and height,
it is a cylinder and you have volume and height
etc.

What formula is used to calculate a circle?
When the radius is r and the center is at (a,b), the formula is (r*cos(θ) + a , r*sin(θ) +b). When the circle is rooted at (0,0), the formula is simply (r*cos(θ) , r*sin(θ)). This is the polar-coordinates system.
