# Area & Circumference of Circle

Videos and lessons to help Grade 7 students know the formulas for the area and circumference of a circle and use them to solve problems; give an informal derivation of the relationship between the circumference and area of a circle.

Common Core: 7.G.4

### Suggested Learning Targets

• I can state the formula for area and circumference of a circle.
• I can use the formula for the area of a circle to solve problems.
• I use the formula for the circumference of a circle to solve problems.
• I can identify or produce a logical conclusion about the relationship between the circumference and area of a circle (e.g., given three circles with the areas A1>A2>A3, the circumferences satisfy C1>C2>C3).
• I can write my solutions in terms of pi(π), decimals, and fractions.
