Answer:

28.26 ft^2, 18.84 ft

Step-by-step explanation:

We are given a circle with a radius of 3 feet;

[tex]Area of Circle = \pi * ( r^2 ) = \pi * ( 3^2 ) = 9\pi \\[/tex]

[tex]Circumference = 2 * \pi * r = 2 * \pi * ( 3 ) = d * \pi, d - diameter,\\Circumference = d * \pi = 6\pi[/tex]

[tex]If \pi = ( About ) 3.14 -\\ Solution ; Area = ( About ) 28.26 , & Circumference = ( About ) 18.84[/tex]

Area= 28.27ft2

Circumference= 18.85ft

Sorry I couldn't write it how your teacher wanted it but that part didn't make sense to me. Here are the answers anyway. Hope it helped!
