Use the value 3.14 for , and do not round your answers. Be sure to include the correct units in your answers.

Answer 1

Area & Circumference = 12.56ft

Explanation:

The formula for area of a circle is πr^2

r = 2

π = 3.14

(3.14) x (2^2)

(3.14) x (4) = 12.56

The formula for circumference of a circle is 2πr

r = 2

π = 3.14

2 x (3.14) x 2

(3.14) x (4) = 12.56
