Mathematics (2019) Grade(s): 7

MA19.7.20

Explain the relationships among circumference, diameter, area, and radius of a circle to demonstrate understanding of formulas for the area and circumference of a circle.

UP:MA19.7.20

Vocabulary

  • Diameter
  • Radius
  • Circle
  • Area
  • Circumference
  • π

Knowledge

Students know:
  • that the ratio of the circumference of a circle and its diameter is always π.
  • The formulas for area and circumference of a circle.

Skills

Students are able to:
  • use the formula for area of a circle to solve problems.
  • Use the formula(s) for circumference of a circle to solve problems.
  • Give an informal derivation of the relationship between the circumference and area of a circle.

Understanding

Students understand that:
  • area is the number of square units needed to cover a two-dimensional figure.
  • Circumference is the number of linear units needed to surround a circle.
  • The circumference of a circle is related to its diameter (and also its radius).
