Question

The radius of a circle is 7 feet. What is the approximate distance around the circle using 3.14 for pi?

Answer 1

Circumference formula = c= (pi)d
Radius = 2r=d —-> 2(7)=14
C= (3.14)(14)
C=43.96 feet

Answer 2

43.96

Explanation:

To find the circumference of a circle, you would need to use this formula:

`c = 2\pi r`

Since we already know what the radius is, all we need to do is substitute variables for numbers:

`2`·
`3.14`·
`7`

`6.28`·
`7`

`43.96`

Hope this helps!
