The exterior surface of a farm silo needs to be painted. if one gallon of paint covers 224 square feet, what is the minimum numb
1 answer:
The gallons needed to paint the silo is 10.
<h3>How many gallons is needed to paint the silo?</h3>A cylinder is a three-dimensional object. It is a prism with a circular base. The total surface area of cylinder can be determined by adding the area of all its faces.
Total surface area of the cylinder excluding its base = 2πrh +πr²
Where:
- r = radius
- h = height
TSA = (2 x 3.14 x 10 x 30) + (3.14 x 10²)
314 + 1884 = 2198 ft²
Number of gallons needed = 2198 / 224 = 9.81 = 10 gallons
