What is the area of a circle?

$A = \pi r^2$

What is the Pythagorean Theorem?

$a^2 + b^2 = c^2$

What are related rates?

Using derivatives to calculate unknown quantities in relation to other quantities and their rates of change.

What quantity is typically related to other quantities in related rates problems?

Time.

Why is it important to draw a diagram when solving related rates problems?

Provides a visual understanding of the problem and helps in finding the appropriate formula.

What is the first step in solving a related rates problem?

Determine the known and unknown quantities from the problem.

What is the second step in solving a related rates problem?

Model the relationship between quantities using a formula.

What is the third step in solving a related rates problem?

Apply derivative rules with respect to the unknown quantity (typically time).

What is the fourth step in solving a related rates problem?

Substitute known quantities into the derived equation and solve for the remaining quantities.

What does $\frac{dr}{dt}$ represent in a related rates problem?

The rate of change of the radius with respect to time.

What does $\frac{dA}{dt}$ represent in a related rates problem?

The rate of change of the area with respect to time.

Why is implicit differentiation used in related rates problems?

Because we are differentiating with respect to a variable (usually time) that the variables in the equation are dependent on.
