I need help with that calculation.. ( IN JAVA)

Write a program to calculate the cost to paint a water tower (inside and out). The water tower is a cylinder 15m high with a diameter of 5m. The wall and top thickness is 20 cm. The bottom of the tank is 1 ft off the ground. A gallon of paint covers 5 square feet and costs $24.95. Labor costs $5.25 per square foot at or below 6ft and S10 per sq ft above 6ft. Paint inside, outside, top and bottom. Program layout and output(s) should make the algorithm used clear. All calculations should be done in the program. Output appropriate intermediate results.
