Question

In official NHL hockey puck is shaped like a cylinder with a diameter of 3 inches and a volume of 7.1 in.³. What is the height of the hockey puck?

Answer 1

Answer:

1 inch

Step-by-step explanation:

The formula for the volume of a cylinder:

V = πr²h, where r=radius and h = height

Using 7.1 for 'V' and 1.5 for 'r' (1/2 of the diameter), we can fill in the values and solve for 'h':

7.1 = π(1.5)²h or 7.1 = 7.065h

h = 1 inch
