t=\frac{d}{r}

t=\frac{r}{d}

r\cdot t=d

d\cdot t=r

d=\frac{r}{t}

t=r\cdot d

r = \frac{t}{d}

d=\frac{t}{r}

rt=\frac{d}{t}

d\cdot r=\frac{t}{r}

The equation for the volume of a cylinder is V=\pi r^{2}h where V is the volume, r is the radius, and h is the height of the cylinder. Which equation correctly expresses the constant \pi as a ratio of other terms?

\pi=\frac{r^{2}h}{V}

\pi=\frac{V}{r^{2}h}

\pi=\frac{V}{h}\sqrt{r}

It is not possible to express \pi in terms of variables, because the variables can change their value, but \pi is always the same number.

In finance, the amount of money you deposit or borrow is often called a "principle", and the amount of interest you earn or owe is calculated as a percent of that principle amount. If interest is "simple" (or "non-compounded"), we can use the formula P=Irt, where P and I represent the principle and interest, r the interest rate per time period, and t the number of time periods, Which equation will give the rate in terms of the other factors?

r=\frac{P}{It}

r=P-It

r=\frac{It}{P}

r=\frac{P-I}{t}
