Answer 2

Hello! Our answer is C = 62.8 ft.

`\large\text{Explanation:}`

We are asked to find the circumference of a circle whose diameter is 20 ft.

To find the circumference of a circle, use this formula:

`\bf{C=\pi d}`

Where c = circumference & d = diameter.

• 
  `\sf{C=\pi*20}`

Multiply:

`\sf{C=62.8\:ft}`

`\therefore` rounded to the nearest tenth, the circumference is 62.8 ft
