White board work You will be able to solve for area and circumference of circles by using the appropriate formula

The formula (algorithm) to find the area of a circle:

Find the AREA If: Radius is 7 m

Find the AREA If: Diameter is 7 m

Find the AREA If: Radius is 4.5 m

Find the AREA If: Diameter is 2.5 m

Find the AREA If: Diameter is 7 m 2

Center

Find the Circumference if: C = π d C = 3.14 x 5 C = 15.7 m Radius is 2.5 m

Find the Circumference if: C = π d C = 3.14 x 18 C = m Diameter is 18 m

Find the Circumference if: C = π d C = 3.14 x 2.6 C = m Radius is 1.3 m

Final the and the Final Review: Find the Circumference and the Area if the… C = π d C = 3.14 x 10.4 C = m Radius is 5.2 m A = π r A = 3.14 x (5.2 x 5.2) A = 3.14 x A = m 2 2
