HELP!! Please answer this! :(

Step-by-step explanation:

The fence posts are cylindrical. To determine how much paint is needed to paint the surfaces if each fence post, we need to determine the total surface area of each fence post. The formula for determining the total surface area of a cylinder is expressed as

Total surface area = 2πrh + 2πr²

r and h represents the radius and height of each fence post.

From the information given,

h = 7 feet

Diameter = 1 foot

r = diameter/2 = 1/2 = 0.5 foot

Total surface area = (2 × 3.14 × 0.5 × 7) + (2 × 3.14 × 0.5²)

= 23.55 square feet

Since the number of fence posts is 11, the total amount of paint needed should cover

23.55 × 11 = 259.05 square meters
