Question

The radius of a circle is 12.1 ft. Find the circumference to the nearest tenth}to the nearest tenth

Answer 1

Given :-

• Radius of circle = 12.1 ft

To Find :-

Circumference

Solution :-

As we know that

`\boxed { \bf \: Circumference = 2\pi \: r}`

`\tt \: C = 2 * (22)/(7) * 12.1`

`\tt \: C = (44)/(7) * 12.1`

`\huge \bf \pink{C = 76.0}`

Answer 2

76 ft

Explanation:

Use the circumference formula, C = 2
`\pi`r

Plug in the radius:

C = 2
`\pi`r

C = 2
`\pi`(12.1)

C = 76.0

So, the circumference is 76 ft
