I'm not good at Surface Area, and I really need to figure out how to do this. :[
Can someone work it out step by step?
MUCH APPRECIATED!! <33
Problem:
You have been hired to paint the Greensboro, Ga. historic water tower green.
The tower has a cylindrical base that is 12 feet around and 85 feet high. The top is sphere and is 300 feet around.
A gallon can of green paint on average covers 200 ft2(feet squared) and cost about $35 per gallon.
How much would it cost to paint the entire water tower?
