X=4 Im not sure if this helps or not I dont really understand what your looking for
Hello!
A(r) is a function. It takes a value of r, and from that calculates the value A. In this case, it takes the value of a radius, and <u>depending on what that value is</u>, it calculates the area.
A(3) would therefore represent the area based off of a radius of 3.
Hope this helps!
