Question

 larry has a propane tank in the shape of a cylinder with a hemisphere on each end, the total length of the tank is 16 feet. the width of the tank is 6 feet. he intends to paint the outside of the tank using paint that covers 175 square feet per gallon. the paint cost 29.99 per gallon. Find the total cost of this paint job (Assume that larry can buy the exact amount of paint that he needs) use a single expression to calculate the cost save all rounding until the final step. show two decimal places

Answer 1

First the main part of the tank

 

Surface area = circumference time length

SA = 6π(16)

SA = 96π

 

The two hemispheres make a sphere

 

SA = 4πr²

SA = 4π(9)

SA = 36π

 

Total Area = 132π

 

Divide this by 175 to determine the number of gallons of paint.

Multiply that by 29.99 for determine the cost of the paint.
