A farmer wants to paint a silo with red paint. He only wants to paint the sides. If the tank has a height of 13 maters and a diameter of 10 meters, how much paint will he need?

Step-by-step explanation:

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
