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

Respuesta :

The perimeter of a circle is calculated with 2πr
The r stands for radius. The radius is half of the diameter.
So r=2.25
Plug it in 2π(2.25)
It was simplify to 4.5π
Which would simplify down to 14.14 miles rounding to the nearest hundredth.
