Question

question 14 (multiple choice worth 1 points) (00.02r mc) the picture shows a container that sue uses to freeze water. what is the minimum number of identical containers sue would need to make 2,000 cm³ of ice? (use π = 3.14.)

Explanation:

Step1: Calculate volume of one container

The volume formula for a cylinder is $V = \pi r^{2}h$. Given radius $r=\frac{4}{2}=2$ cm and height $h = 6$ cm. So $V=3.14\times2^{2}\times6=3.14\times4\times6 = 75.36$ $cm^{3}$.

Step2: Find number of containers

Divide the total volume of ice needed by volume of one container. $\text{Number of containers}=\frac{2000}{75.36}\approx26.54$. Since we can't have a fraction of a container, we need to round up to the next whole - number. So the minimum number of containers is 27.

Answer:

27
