Question

Medal and fan,
Can someone check this answer? I said 27.
The picture below shows a container that Sue uses to freeze water:

A cylinder is shown with base diameter of 4 centimeters and the height as 6 centimeters.

What is the minimum number of identical containers that Sue would need to make 2,000 cm3 of ice? (Use π = 3.14.)
12
18
27
7

Answer 1

Use pi d squared over 4 to find the area of the circle and then multiply by the length 6 to find the volume. The area is 4 pi or 12.566 and multiply this by 6 to give 75.39.

Now divide 2000 by 75.39 to get 26.53 meaning she would in fact need 27 as it would not all fit into 26.
