Answer:

Circumference is 18.84 feet. Area is 28.26 square feet.

Step-by-step explanation:

Given:

Radius of the circle, r=3\textrm{ ft}

The value of \pi is 3.14.

Now, circumference of a circle of radius r=3 is given as:

Circumference=2\pi r=2\times 3.14\times 3=18.84\textrm{ ft}

Also, area of the circle of radius r=3 is given as:

Area=\pi r^{2}=3.14\times (3)^{2}=3.14\times 3\times 3=28.26\textrm{ }ft^{2}

Therefore, the circumference of the circle is 18.84 feet and area of the circle is 28.26 square feet.
