Answer
The constant of variation, in order, of the variation equations are:
$\boxed{4, 2, 4\pi, \frac{4}{3}\pi, \frac{1}{2}, \frac{1}{3}\pi}$
Work Step by Step
The constant of variation in $P=4s$ is $4$.
The constant of variation in $d=2r$ is $2$.
The constant of variation in $S=4\pi{r^2}$ is $4\pi$.
The constant of variation in $V=\frac{4}{3}\pi{r^3}$ is $\frac{4}{3}\pi$.
The constant of variation in $A=\frac{1}{2}bh$ is $\frac{1}{2}$.
The constant of variation in $V=\frac{1}{3}\pi{r^2h}$ is $\frac{1}{3}\pi$.
Thus, the constant of variation, in order, of the variation equations are:
$\boxed{4, 2, 4\pi, \frac{4}{3}\pi, \frac{1}{2}, \frac{1}{3}\pi}$
