Find the circumference and the area of a circle with radius 5ft. Use the value 3.14 for π, and do not round your answers. Be sure to include the correct units in your answers.

Answer:

Circumference = 31.4 feet

Area= 78.5 sq. feet.

Step-by-step explanation:

The circumference of a circle is its outer length (or perimeter).

The area of the circle is the area inside the circle.

Each has its own formula. We write and plug in 5 into r (the radius) and find our answer.

Circumference = [tex]2\pi r = 2(3.14)(5) = 31.4[/tex] = 31.4 feet

and

Area = [tex]\pi r^2 = (3.14)(5)^2 = 78.5[/tex] square feet
