Elena wonders how much water it would take to fill her cup. She drops her pencil in her cup and notices that it just fits diagon

ollegr [7]

Answer:

<h2>The cup can hold 240π cubic centimeters of water.</h2>

Step-by-step explanation:

Let's assume the cup is a cylinder. The pencil length is simulates a diagonal (hypothenuse), which forms a right triangle with the height of the cylinder and the diameter at the bottom. So, we apply Pythagorean's Theorem.

$17^{2} =15^{2} + d^{2}$

Solving for $d$ , we have

$289 - 225 = d^{2} \\d=\sqrt{64} \\ d=8$

Therefore, the diameter of the cylinder is 8 centimeres, which means its radius is 4 centimeters by definition.

The volume of a cylinder is defined as

$V= \pi r^{2} h$

Where $r$ is the radius and $h$ is the height. Replacing values, we have

$V= \pi \times 4^{2} \times 15 =\pi \times 16 \times 15\\V=240\pi \ cm^{3}$

Therefore, the cup can hold 240π cubic centimeters of water.
