Answer :
ANSWER
• Circumference: 18.84 ft
,• Area: 28.26 ft²
EXPLANATION
The circumference of a circle of radius r is,
[tex]C=2\pi r[/tex]In this case, the radius is r = 3 ft and we have to use 3.14 for π,
[tex]C=2\cdot3.14\cdot3ft=18.84ft[/tex]Hence, the circumference of this circle is 18.84 feet.
The area of a circle of radius r is,
[tex]A=\pi r^2[/tex]In this case, r = 3 ft and π = 3.14,
[tex]A=3.14\cdot3^2ft^2=28.26ft^2[/tex]Hence, the area of this circle is 28.26 square feet.
