ANSWER

• Circumference: 18.84 ft

,

• Area: 28.26 ft²

Step-by-step explanation

The circumference of a circle of radius r is,


C=2\pi r

In this case, the radius is r = 3 ft and we have to use 3.14 for π,


C=2\cdot3.14\cdot3ft=18.84ft

Hence, the circumference of this circle is 18.84 feet.

The area of a circle of radius r is,


A=\pi r^2

In this case, r = 3 ft and π = 3.14,


A=3.14\cdot3^2ft^2=28.26ft^2

Hence, the area of this circle is 28.26 square feet.
