The perimeter of crater lake is 17.27 miles.
Step-by-step 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 =
× diameter
the value of
= 3.14
Or, p =
× d
Or, p =
× 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
