3장, 문제 3.11.7a
The volume V of a sphere of radius r changes over time t.
a. Find an equation relating dV/dt to dr/dt.
검증된 단계별 안내1
Start with the formula for the volume of a sphere: V = (4/3)πr^3.
Differentiate both sides of the equation with respect to time t to find the rate of change of volume with respect to time, dV/dt.
Apply the chain rule to differentiate the right side: dV/dt = d/dt[(4/3)πr^3] = (4/3)π * 3r^2 * (dr/dt).
Simplify the expression: dV/dt = 4πr^2 * (dr/dt).
This equation shows that the rate of change of the volume of the sphere with respect to time, dV/dt, is related to the rate of change of the radius with respect to time, dr/dt, by the factor 4πr^2.

Related Rates
Related rates involve finding the rate at which one quantity changes in relation to another. In this context, we are interested in how the volume of a sphere changes with respect to time as the radius changes. By applying the chain rule, we can relate the rates of change of volume and radius.

Intro To Related Rates
Volume of a Sphere
The volume V of a sphere is given by the formula V = (4/3)πr³, where r is the radius. This formula is essential for deriving the relationship between the volume and the radius. Understanding how volume depends on radius is crucial for applying calculus to find the rate of change of volume with respect to time.

Chain Rule
The chain rule is a fundamental principle in calculus used to differentiate composite functions. In this problem, we apply the chain rule to express dV/dt in terms of dr/dt. This allows us to find how the volume's rate of change is influenced by the radius's rate of change, linking the two quantities effectively.
