What is the equation of a right circular cylinder with radius 3?
Use the formula $x^2 + y^2 = r^2$.
Describe what happens to the shape if the radius decreases.
Think about how the radius relates to the overall size of circles.
The equation represents a cylinder. What is its radius?
Recall the relationship between radius and the equation.
A right circular cylinder is also known as what?
Remember the properties that differentiate these shapes.
A cylinder's height is tripled, but its radius remains constant. Describe how this changes its volume.
Apply the volume formula: $V = ext{Base Area} \\times ext{Height}$.
If two cylinders have the same diameter but one is twice as tall as the other, how does their volume compare?
Use the volume formula to reason through the comparison.
