Circles are a basic figure in geometry and a sound knowledge about their properties would help you strengthen your core concepts of Maths. The diagram below depicts four terms you should already know: circumference, centre, radius, and diameter. Know and use the formulas for area and circumference of a circle (Common Core 7.G.4) 7.G.3: Identify the two-dimensional shapes that make up the faces and bases of three-dimensional shapes (prisms, cylinders, cones, and pyramids) 3. Here’s why you should use circle worksheets with answers It helps students understand 2D shapes and radius, diameter, and circumference measurements. ![]()
