A cylindrical hockey puck is 1in high and 3in in diameter. What is its volume in cubic inches?
To find the volume of a cylindrical object, you need to use the formula for the volume of a cylinder, which is given by:
Volume = π * r² * h
Where:
- π is a mathematical constant approximately equal to 3.14159.
- r is the radius of the base of the cylinder.
- h is the height of the cylinder.
In this case, the hockey puck has a diameter of 3 inches, which means the radius is half of that, so the radius is 1.5 inches (3/2 = 1.5). The height of the puck is given as 1 inch.
Now you can substitute these values into the formula:
Volume = π * 1.5² * 1
Calculating this, you have:
Volume = 3.14159 * 1.5² * 1
Volume ≈ 7.06858 cubic inches
So, the volume of the cylindrical hockey puck is approximately 7.06858 cubic inches.
