Please type your subject in the School Subject box. Any other words are likely to delay responses from a teacher who knows that subject well.
Of a computer disk?
Volume = pi* r^2* h
pi = 3.1416
r = radius = distance from center to edge of CD
h = height = the short distance from top to bottom of the CD
Does this help?
Pi times r squared
To find the volume, height, and radius of a CD, you will need some measurements and formulas. Here's a step-by-step guide:
1. Measure the diameter (width) of the CD using a ruler. This will be the same as the diameter of the circular shaped CD.
2. Divide the diameter by 2 to find the radius. The radius is half of the diameter.
3. Measure the thickness of the CD using a ruler. This will give you the height (also known as the thickness).
4. With these measurements, you can calculate the volume of the CD using the formula for the volume of a cylinder: V = πr^2h, where V represents the volume, π is a mathematical constant approximately equal to 3.14, r is the radius, and h is the height (thickness) of the CD. Plug in the values you obtained in steps 2 and 3 into the formula and calculate the result. The volume will be in cubic units, such as cubic inches or cubic centimeters.
So, by measuring the diameter, dividing it by 2 to find the radius, measuring the thickness, and plugging these values into the volume formula, you can find the volume, height, and radius of a CD.
