Question

Crater lake in Oregon is shaped like a circle with a diameter of about 5.5 miles. How far is it around the perimeter of crater lake?

Answer 1

The perimeter of crater lake is 17.27 miles.

Explanation:

Given as :

The shape of the lake is like a circle

The diameter of lake = d = 5.5 miles

∵ shape pf lake is circle, so the diameter of circle = d = 5.5 miles

Let The perimeter of crater lake = p miles

Now, As we know

The perimeter of circle =
`\pi` × diameter

the value of
`\pi` = 3.14

Or, p =
`\pi` × d

Or, p =
`\pi` × 5.5 miles

Or, p = 3.14 × 5.5 miles

∴ p = 17.27 miles

So, The perimeter of circle = perimeter of lake = p = 17.27 miles

Hence, The perimeter of crater lake is 17.27 miles. Answer
