Finding the Radius and Diameter in Circles WORKSHEET
Finding the Radius and Diameter in Circles WORKSHEET DESCRIPTION
This worksheet is designed to help learners practice the skill of working backwards to find a radius or diameter of a circle when the area or circumference is given. Section A begins with some fill in the blank missing number questions, where learners will be finding a missing diameter or radius from a circumference calculation. Section B then gives some circles with known circumferences, and learners need to find the missing diameter or radius. Section C then provides some more fill in the blank questions linked to the area formula, before section D presents some circles with known areas for learners to find the missing radius or diameter. Section E then gives some semicircles and sectors with a known area for learners to find a missing value. The worksheet ends with section F providing some problem solving questions.
All worksheets are created by the team of experienced teachers at Cazoom Math.
