Answer:

28.26 ft^2, 18.84 ft

Explanation:

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


Area of Circle = \pi * ( r^2 ) = \pi * ( 3^2 ) = 9\pi \\


Circumference = 2 * \pi * r = 2 * \pi * ( 3 ) = d * \pi, d - diameter,\\Circumference = d * \pi = 6\pi


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