Question

The radius of a circular hat is 3.7 inches. Find the circumference. Use 3.14 for π. (1 point)

1.85 in.
11.618 in.
23.236 in.
22.2 in.

Answer 1

The answer is 23.236

the equation for circumference is C=2(pie)r

So you take 2x3.14 which equals 6.28.

Then you multiply 6.28 by 3.7 to get your answer.

Answer 2

The circumference is
`23.236\ in`

Explanation:

we know that

The circumference of a circle is equal to

`C=2\pi r`

we have

`r=3.7\ in`

substitute

`C=2(3.14)(3.7)=23.236\ in`
