Question

What is the volume of the cylinder below?

Answer 1

C. 2160π units³

Explanation:

Volume of a cylinder is given by the formula :

V = πr²h

Substituting values given gives us :

V = π(12)²(15)

V = π(144)(15)

V = 2160π units³ (since it is volume)

Answer 2

`\boxed{\sf{C. \quad 2160\pi \quad units^3}}`

Explanation:

It is necessary to use their formula to solve this problem with the volume of the cylinder.

Volume of the cylinder formula:

`\Longrightarrow: \sf{V=\pi r^2h}}`

`\sf{12^2(15)}`

Solve.

Use the order of operations.

PEMDAS stands for:

• Parentheses
• Exponents
• Multiply
• Divide
• Add
• Subtract

First, solve with exponents.

`\sf{12^2=12*12=144}`

Then, rewrite the problem down.

144(15)

Multiply.

`\sf{144*15=\boxed{\sf{2160}}}`

• Therefore, the correct answer is C. 2160π units³.
