Question

One type of stone formation found in Carlsbad Caverns in New Mexico is called a column. This stone formation connects to the ceiling and the floor of a cave.

a. What is the radius (to the nearest tenth of a foot) of a cylindrical column that has a circumference of 7 feet? 8 feet? 9 feet?

Answer 1

8ft =Radius of (approx) ≈1.274

Answer 2

7ft = Radius of ≈1.114
C=2pir
7=2pir
7/3.14=2r (diameter)
2.229/2 =r
1.114 =r

8ft= Radius of ≈1.274


9ft= Radius of ≈1.433
