What do the $x$ and $y$ axes typically represent in a 3D Cartesian system?
In a 3D Cartesian system, the $x$ and $y$ axes typically represent lateral space (length and width).
What does the $z$ -axis typically represent in a 3D Cartesian system?
In a 3D Cartesian system, the $z$ -axis typically represents vertical height.
State the expression for the midpoint of two points, $(x_{1}, y_{1}, z_{1})$ and $(x_{2}, y_{2}, z_{2})$ in 3D.
The expression for the midpoint of two points, $(x_{1}, y_{1}, z_{1})$ and $(x_{2}, y_{2}, z_{2})$ in 3D is $(\frac{x_{1} + x_{2}}{2}, \frac{y_{1} + y_{2}}{2}, \frac{z_{1} + z_{2}}{2})$
This is given in your exam formula booklet.
What is the formula for finding the distance between two points $(x_{1}, y_{1}, z_{1})$ and $(x_{2}, y_{2}, z_{2})$ in 3D?
The distance between two points is calculated using the formula, $d = \sqrt{{(x_{1} - x_{2})}^{2} + {(y_{1} - y_{2})}^{2} + {(z_{1} - z_{2})}^{2}}$
Where:
- $d$ is the distance between two points
- $(x_{1}, y_{1}, z_{1})$ is the set of coordinates for a known point
- $(x_{2}, y_{2}, z_{2})$ is the set of coordinates for another known point

- $r$ is the radius of the circular base of the cone
- $h$ is the vertical (perpendicular) height of the cone
This is given in your exam formula booklet.
What is the formula for the volume of a right pyramid?
The formula for the volume of a right pyramid is $V = \frac{1}{3} A h$
Where:
- $V$ is the volume of the pyramid
- $A$ is the area of the base of the pyramid
- $h$ is the vertical (perpendicular) height of the pyramid
This is given in your exam formula booklet.
What is the formula for the volume of a sphere?
The formula for the volume of a sphere is $V = \frac{4}{3} π r^{3}$
Where:
- $V$ is the volume of the sphere
