Understanding the applications of using area of circles is a critical skill that has gone into just about every major engineering feat since the dawn of architecture. Many of today's standing structures including bridges and tunnels have this skill to thank for standing strong in the face of everything that Mother Nature could throw at it. In order to determine the area of a circle you must understand two simple measures as one of them will have to be given to you or measurable. The first measure you need to understand is diameter. This is the length of a line travels from a point on the circle travels directly through the center of the circle to another point on circle. This is a basic measure of the size of the circle. The measure of radius is the distance travelled from one point on the circle to the direct center. The area of a circle is equivalent to the product of pi and the square of its radius.

Use these worksheets to show how to use given information about a circle to determine, with the use of the proper formula, that circle's radius and circumference. In this section we will throw in a mix of algebra and higher level critical thinking skills when working with these problems. Students should be able to navigate this material quickly and efficiently. This section of our site will really get the kids thinking about determining the area of given sectors and segments of circles using the values of the angles, the radius, the length of an arc, etc. Make sure to print the first three sheets as they are the key to learning this topic in depth.
