Grade 7 - Shape and Space
Standard 7.SS.1 - Practice calculating the area, radius, diameter and circumference of a circle.
Included Skills:
Demonstrate an understanding of circles by:
• describing the relationships among radius, diameter and circumference.
• relating circumference to pi.
• determining the sum of the central angles.
• constructing circles with a given radius or diameter.
• solving problems involving the radii, diameters and circumferences of circles.
• Illustrate and explain that the diameter is twice the radius in a given circle.
• Illustrate and explain that the circumference is approximately three times the diameter in a given circle.
• Explain that, for all circles, pi is the ratio of the circumference to the diameter (C/d) and its value is approximately 3.14.
• Explain, using an illustration, that the sum of the central angles of a circle is 360°.
• Draw a circle with a given radius or diameter, with and without a compass.
• Solve a given contextual problem involving circles.
