Answer:
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

Step-by-step explanation:

Answer: Distance = 15km ; Displacement ≅ 11'2km
Step-by-step explanation:
In Physics when we speak of distance we refer to the space traveled that is always measured on the trajectory, while displacement refers to the space from an initial position to a final position regardless of the path. When the path is a straight line, the space traveled is equal to the module of the displacement.
Distance: 5km + 5km + 5km = 15km (Red lines)
Displacement² : (10km)² + (5km)² = 100km² + 25km² = 125km²
Displacement : √125km² ≅ 11'2km (Blue line)
