Question

# Scientists are drilling a hole in the ocean floor to learn more about the Earth's history. Currently, the hole is in the shape of a cylinder whose volume is approximately 3500 cubic feet and whose height is 4.8miles. Find the radius of the hole to the nearest hundredth of a foot. (Hint: Make sure the same units of measurement are used.)

Answer

6.77 feet

- Convert height to feet. A:4.8 miles is equal to 25,344 feet.
- Use the formula for volume of a cylinder (V=πr^2h) to solve for radius. A:r is equal to the square root of (V/πh), which, when plugged in with our given values, is approximately 6.77 feet.
