Answer 1

Circumference is 18.84 feet. Area is 28.26 square feet.

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* 3.14* 3=18.84\textrm{ ft}`

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

`Area=\pi r^(2)=3.14* (3)^(2)=3.14* 3* 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.
