This generator makes worksheets for calculating the radius, diameter, circumference, or area of a circle, when one of those is given (either radius, diameter, circumference, or area is given). They can be made in PDF or html formats.
Question 3: Work out the area of the following circles. Give your answers to 1 decimal place. (a) A circle with radius 9cm (b) A circle with radius 12m
This worksheet is perfect to use when introducing the area of a circle. Throughout the worksheet, levels of scaffolding are added and removed at appropriate times to aid learners in consolidating the formula for finding the area. Sections A and B provide circles with a given radius, with sections C and D providing the diameter.
