To recap, the circumference is the distance around the outer edge of a circle and can be found using C = 2πr. The area is the space enclosed by the circle's boundary and can be found using A = πr². Remember to use the correct formula and substitute the radius value to find the respective values.

Now that you have a clear understanding of circumference and area of circles, go ahead and apply this knowledge in solving real-world problems or exploring more exciting mathematical concepts.
