Question

A circle has a circumference of 907.46 units.
What is the diameter of the circle?

Answer 1

`d=288.8535units`

Explanation:

Given:

`C=907.46 units`

With the information given, we can use the circumference formula to find the diameter. We need to solve for
`r`.

`C=2\pi r`

`907.46=2\pi r`

`453.73=\pi r`

`144.426744658=r`

We just found the radius. To find the diameter, we have to multiply the radius by 2.

`2r=d`

`2(144.426744658)=d`

`d=288.853489316`

This would be your final answer, you should probably round to the hundredths or thousandths place.

Answer 2

d≈288.85

C Circumference
