Question

7-th grade math question :

The circumference of a circle is 25.12 feet. What is the circle's diameter?
|__|feet

Answer 1

Circumference is pi multiplied by diameter

therefore we can set up the equation

`\pi d=25.12`

we can call
`\pi` 3.14

so then

`3.14d=25.12`

divide both sides by 3.14

`\bold{d=8}`
