Question

The circumference (C) of a circle is 16 cm. Which formula can you use to find the diameter (d) if you know that C = πd?

Answer 1

okay i'm confused on the question but i do know the answer of the diameter
if that help the diameter would be d=5.09cm
i hope this helps

Answer 2

The circumference (C) of a circle is 16 cm.

Circumference C =
`\pi *d`

The approximate value of
`\pi` is 3.14

Given C = 16

We plug in 16 for C and 3.14 for
`\pi` in the formula C =
`\pi *d` . then solve for d

C =
`\pi *d`

16 = 3.14 * d

'd' is multiplied with 3.14. To get 'd' alone we divide by 3.14 from both sides

`(16)/(3.14) = (\pi*d)/(3.14)`

5.09554 = d

So diameter of the circle = 5.1 cm
