Grade 7 - Shape and Space

Standard 7.SS.1 - Practice calculating the perimeter and radius of a circle based on the dimensions of a quarter circle.

Included Skills:

Demonstrate an understanding of circles by
describing the relationships among radius, diameter, and circumference of circles
relating circumference to pi (π)
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 circle.
Illustrate and explain that the circumference is approximately three times the diameter in a circle.
Explain that, for all circles, pi (π) 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 or without a compass.
Solve a contextual problem involving circles.
