Meteor Crater, located near Flagstaff, Arizona, is a circular crater with a circumference of 2.32 miles. What is the
approximate diameter of the crater?

The approximate diameter of the crater is 0.74 mile.

Step-by-step explanation:

Circumference of a circle(C)=2*π*r(radius of the circle)

2.32 miles=2π*r

or, r=2.32 miles/2π

So, r=0.369 mile

Then,

d=2r

d=2*0.369 mile

So, d= 0.74 mile

the least common denominator is 40

the correct answer is d
