Question

What is the formula for a cylinder again?

Answer 1

Answer: V=pi*r^2

Explanation:

Answer 2

Explanation:

The following formula's can be used to find the volume, surface area, and lateral area of a cylinder.

`\boxed{\left\begin{array}{ccc}\text{\underline{Volume of a Cylinder}}\\\\V=\pi r^2 h\end{array}\right}`

Where:

• "V" represents the volume of the cylinder
• "π" (pi) is a mathematical constant approximately equal to 3.14159
• "r" is the radius of the base of the cylinder
• "h" is the height of the cylinder

`\boxed{\left\begin{array}{ccc}\text{\underline{Surface Area of a Cylinder}}\\\\SA=2\pi rh+2 \pi r^2\end{array}\right}`

Where:

• "SA" represents the surface area of the cylinder

• "π" (pi) is the mathematical constant

• "r" is the radius of the base of the cylinder

• "h" is the height of the cylinder

`\boxed{\left\begin{array}{ccc}\text{\underline{Lateral Area of a Cylinder}}\\\\LA=2\pi rh\end{array}\right}`

Where:

• "LA" represents the lateral area of the cylinder

• "π" (pi) is the mathematical constant

• "r" is the radius of the base of the cylinder

• "h" is the height of the cylinder

What is the difference between surface and lateral area?

The lateral area refers to the surface area excluding the top and bottom circular bases of the cylinder.
