A circle is a shape that looks like a round ball or a pizza. The circumference is like a ribbon or string that goes all the way around the circle’s edge. It’s like measuring how long the curve of the circle is. The area is like the space inside the circle. It’s the amount of space that the circle covers.

To figure out the area of a circle, someone named Archimedes came up with a special formula a long time ago. The formula is A = πr². The “r” stands for the radius, which is how long it is from the center of the circle to the edge. The “π” is a special number that’s always the same (about 3.14159). If we multiply the radius by itself (r²) and then multiply that by π, we get the area of the circle. It’s like a magic trick!
