Question

The picture below shows a container that Jeff uses to freeze water: A cylinder is shown with base diameter of 8 centimeters and the height as 10 centimeters. What is the minimum number of identical containers that Jeff would need to make 2,000 cm3 of ice? (Use π = 3.14.)

Answer 1

Okay, first we need to figure out what one would make. We need to figure out the area of the base x height. The diameter is 8 so we will cut that to 4 so we can do piR2! 3.14x16 would be 50.24. Then we mutiply that by 10 to get 502.4cm3! Okay, now we would divide 2000/502.4 to find out how many times we would have to make the containers to get to 2000. The answer is 3.98, which we will have to round up since its asks for the minimum and you cant make a container 3.98 times. So the answer is 4!
