Problema Solution
The Blue Hole is a cylindrical trench located on Lighthouse Reef Atoll, an island off the coast of Central America. It is approximately 1000 feet wide and 400 feet deep.
A) find the volume of the Blue Hole
B) about how many gallons of water does the Blue Hole contain? (1 ft^3= 7.48 gallons)
Answer provided by our tutors
diameter = 1000 ft
height = 400 ft
A) V = (pi)(r^2)(h)
V = (pi)(500^2)(400) = 3.14(10^8) cubic feet
B) (7.48 gal/cubic foot)(3.14e8 cubic feet) = 2.35(10^9) gallons
