Circumference and Area of Circle Worksheets
This page contains worksheets in finding area and circumference of a circle with all possible combinations. There are three levels Easy, Medium and Hard. Easy worksheets required exact answers with radius ranging from 1 to 25. Medium worksheets required rounding answers to tenth place value with radius ranging more than 25 but less 100. Hard worksheets contain the radius in decimals and required answers rounded to two decimal places. Use pi = 3.14 wherever required.
Area from Radius
Applying the formula, Area = pi * r2 , find the area of each circle.
Area from Diameter
Find the radius from diameter and apply the formula to find the area of a circle.
Area from Radius or Diameter
Each worksheet has 9 problems finding area of a circle with the known radius or diameter. Two simple word problems and one story problem included.
Area and Circumference: Combined Review
These are the perfect review worksheets in finding both area and circumference of the circle.
Radius or Diameter from Area
Dividing the area by pi or 3.14, you get r2. Taking the square root, you get radius. Solve each problem based on this technique.
Area from Circumference
Find the area from the circumference of each circle. Word problems included to understand real life application.
Area between Concentric Circles (or ring)
Find the area of outer circle and inner circle. Subtract the inner area from the outer area to find the area of the ring.
Circumference from Radius
Applying the formula, Circumference = 2 * pi * r, find the circumference of each circle.
Circumference from Diameter
To find the circumference, multiply diameter with pi value. Each worksheet has 9 problems.
