Question

The picture below shows a container that Rene uses to freeze water: A cylinder is shown with base diameter of 6 centimeters and the height as 8 centimeters. What is the minimum number of identical containers that Rene would need to make 2000 cm3 of ice? (Use π = 3.14.)

Answer 1

The cylinder has base diameter of 6 centimeters and the height, $h$, of 8 centimeters.

Since the base diameter of the cylinder is 6 cm, therefore, it's radius, $r$, will be 3 cm.

Now, we know that the volume, $V$, of such a cylinder will be:

$V=\pi r^2h$

Plugging in the values given we get the volume to be:

$V=\pi(3)^2\times 8=3.14\times9\times8=226.08$ $cm^3$

Since Rene needs to make 2000 $cm^3$ of ice and one cylinder's volume is 226.08 $cm^3$, Rene would need...

$\frac{2000}{226.08}\approx8.846\approx\boldsymbol{9}$ such identical cylindrical containers.
