Question

A circles diameter is 12 inches what is the circles circumference using 3.14 rounded to the nearest tenth

Answer 1

`37.7in.`

Explanation:

The circumference of a circle is:
`C=2\pi r`

However, the question wants us to use 3.14 instead of
`\pi`.

We are given 12 inches as the diameter of the circle.

We want the radius, which is half of the diameter.

The radius of the circle is 6 inches.

Now that we have the radius, we plug and chug.

`C=2*3.14*6in.\\C=6.28*6in.\\C=37.68in.\\`

However, the question wants us to round the answer to the nearest tenth.

Therefore, the new answer is:
`37.7in.`
