Question

He picture below shows a container that Tim uses to freeze water:

Answer 1

You have a formula : $V= \pi r^2h$. You just have to apply it. It would gives : 

$V= \pi (2)^2(8)$
$V=32 \pi$
$V=100.48cm^3$

Now, use your mind. How many would be needed to make 2000 cm3.

$\frac{2000}{100.48}$
$=19.94 = 20$

Therefore the minimum number of identical containers that Tim would need to make 2,000 cm3 of ice is 20 (option D).

Hope this helps !
