What is the net area to be painted, Mathematics

Assignment Help:

An elevated cylindrical shaped water tower is in require of paint. If the radius of the tower is 10 ft and the tower is 40 ft tall, what is the net area to be painted? (π = 3.14)

a. 1,570 ft2

b. 2,826 ft2

c. 2,575 ft2

d. 3,140 ft2

b. To determine the surface area of a cylinder, use the following formula: surface area = 2πr2 + πdh. Thus, the surface area = 2(3.14)(10)2 + (3.14)(20)(40) or 3,140 ft2. If you select b, you found the surface area of the circular top and forgot about the bottom of the water tower. Thus, the bottom of the tower could need painting since the tank is elevated.
