The Silo is cylindrical in shape.
The farmer wants to paint only the sides of the Silo with red paint. This means that the top and bottom of the Silo will not be painted.
The formula for determining the surface area of a cylinder is expressed as
Surface area = 2πr² + 2πrh
Since the top and bottom is not included, the formula becomes 2πrh
From the information given,
h = 13 meters
Diameter = 10 meters
Radius = diameter/2 = 10/2 =
5 meters
Therefore, the amount of paint that would be needed in square meters is
2 × 3.14 × 5 × 13 = 408.2m²
