To find the area of a circle, one must know what the formula is, and what all parts of the formula mean.
The formula for the area of a circle is: πr²
Now we have to understand what each part of the formula means. The pi symbol (π) is the ratio of a circle's circumference to its diameter, and is approximately 3.14. The r, is the radius of a circle, and since the squared sign is above it, that means that it is the radius multiplied by itself.
