Calculating Volume | SkillsYouNeed
As with a circle, you need π (pi) to calculate the volume of a sphere. The formula is 4/3 × π × radius3. You may be wondering how you could work out the radius of a ball. Short of sticking a knitting needle through it (effective, but terminal for the ball!), there is a simpler way. You can measure the distance around the …
Averages: Mean, Median and Mode | SkillsYouNeed
To calculate the mean, you need a set of related numbers (or data set). At least two numbers are needed in order to calculate the mean. The numbers need to be linked or related to each other in some way to have any meaningful result – for instance, temperature readings, the price of coffee, the number of days in a month, the number of ...
How to Find Volume in Chemistry: A Complete Guide
To calculate volume, you need to know the shape and dimensions of the object or substance you are measuring. Here are some of the most common formulas used to calculate volume in chemistry: For a rectangular solid: V = l x w x h, where V is the volume, l is the length, w is the width, and h is the height. For a cylinder: V = πr²h, where …

Introduction to Algebra | SkillsYouNeed
We can turn the two simple equations above into algebraic equations by substituting x for one of the numbers: 2 + 2 = x. We know that 2 + 2 = 4, which means that x must equal 4. The solution to the equation is therefore x = 4. 5 + 3 > 3 + x. We know that 5 + 3 = 8. The equation tells us that 8 is greater than (>) 3 + x.
