Combined figures involving circles
Combined figures involving circles are shapes made by joining a circle part with other geometric shapes such as rectangles, triangles, or semicircles.
Practice This ConceptMain explanation
Teacher explanation
These questions require careful separation of each part. Students must identify which area or boundary belongs to each shape, then add or subtract correctly. The answer depends on breaking the figure into smaller known parts.
Example
A rectangle with a semicircle on one side may need rectangle area plus semicircle area to get the total.
Simple analogy
Split, solve, and join again.
Common confusion
Students often count the same region twice or forget to remove a part that is cut out.
Exam tip
Draw the figure again and label each part before starting calculation. A neat split reduces errors.
