Question

An asteroid hit the earth and created a huge round crater scientist measured the distance around the crater as 78.5 miles what is the diameter of the crater

Answer 1

The distance around the crater in the Circumference=78.5 miles;
The Diameter = Circumference÷π=78.5/π≈24.99 miles
The Diameter is about 25 miles

Answer 2

to find the diameter, you divide the circumference by pi (use 3.14 for pi). 78.8/3.14 = 25.
the diameter should be 25
