When a variable is raised to the power of 1, it is linear.
C = 2pi r is linear. r is raised to the power of 1.
S = pi r^2 is not linear. r is raised to the power of 2.

Puggy is correct: the formula for area is not linear, since it has a second power on the variable (that is, r). Circumference will change with r at the same rate r does, but with area, the area is going to get much bigger much faster than r as r get bigger.

Linear is defined to be when the variable is a power of 1.
C = 2*pi*r is linear.
