Circumference and Area of a Circle Worksheets

This page is a one-stop shop for all your finding area and circumference of a circle exercises. Catering to the learning needs of students in grade 5 through grade 8, these printable worksheets practice the topic pretty much across the board: easy, moderate and hard. The job in the easy set is to calculate the area and circumference of the circles with radius ranging from 1 to 25. The moderate set requires rounding answers to tenth place with the radius of circles ranging between 25 and 100. In the hard worksheets, the radius is rendered in decimal and the task is to round your answers to two decimal places. Use pi = 3.14 wherever necessary. Explore some of these worksheets for free!

Area from Radius
