Question

Find the exact circumference of a circle with the given radius.

7 feet

C =
7 ft.
14 ft.
27 ft.

Answer 1

r = 7 feet

C = 2 π r = 14 π

Answer: 14π feet

Not apparently among the choices.

Answer 2

Answer:
`C=14\pi\text{ feet}`

Explanation:

We know that the circumference of a circle is given by :-

`\text{Circumference}=2\pi r`, where r is the radius of the circle.

Given: The radius of a circle = 7 feet

Then, the circumference of the circle will be:

`\text{Circumference}=2\pi 7\\\\\Rightarrow\text{Circumference}=14\pi\text{ feet}`
