Answer:

Circumference and Area of a Circle

A. Find the circumference of each circle.

Given: 2.5 centimeters

Formula: C = 2πr

[tex]\sf{C = 2πr}[/tex]

[tex]\sf{C = 2(3.14)(2.5)}[/tex]

[tex]\sf{C = 6.28(2.5)}[/tex]

[tex]\boxed{\sf{C = 15.625 \: cm}}[/tex]

B. Find the area of each circle.

Given: 10 centimeters

Formula: A = πr²

[tex]\sf{A = πr²}[/tex]

[tex]\sf{A = 3.14 (10 cm)²}[/tex]

[tex]\sf{A = 3.14 (100 cm²)}[/tex]

[tex]\boxed{\sf{A = 314 cm²}}[/tex]
