Question

A circle has a circumference of 654 units. Approximate the diameter of the circle.

Answer 1

do u have a formula chart if not that would help you get your answer

Answer 2

When you find a diameter of a circle, you probably used this formula:
C =
`\pi`d

If we algebraically manipulate the formula, we get it to find the diameter with a circumference.

Divide both sides by
`\pi`.

C /
`\pi` =
`\pi`d /
`\pi`.

`(C)/( \pi )` = d
d =
`(C)/( \pi )`

We know the circumference is 654 and we will use 3.14 for
`\pi`.

Plug in the values.

d =
`(654)/(3.14)`
d ≈ 208.3

So, the diameter of the circle is about 208.3 units.
