The distance around a circle is 36
meters long. What is the diameter of the
circle?

Answer 1

Answer:
`36/\pi` or approximately 11.4592

Explanation:

The distance around a circle equals its circumference.

The circumference equation is: C = 2
`\pi` * r where r = radius.

Now, we know that the distance around the circle is 36 so C = 36

Using the equation, we have 36= 2
`\pi`*r

Now, we solve for r by dividing by 2
`\pi` to both sides.

r =
`36/2\pi` which equals
`18/\pi` which is approximately 5.7296

Now, since radius is half of the diameter, we need to multiply this by 2.

This finally gives us the answer of diameter =
`36/\pi` which is approximately 11.4592
