It depends on context. R can stand for radius, which is a straight line from the center to the circumference of a circle or sphere. In the the equation d = rt, r stands for rate,
the speed with which something moves, happens, or changes. R can also stand for degrees Rankine, which are not widely used today.
That's the formula for the area of a circle.
The "R" in math means "radical". Therefore, you're gonna have to get the square root of a digit. If you don't get it, pls. comment on this one.
