add up all the numbers, then divide by how many numbers there are.

259.05 sq. ft.

Step-by-step explanation:

The quantity of paint used will be equal to the total surface area of the fence posts.

Since the wooden poles can be represented by closed cylinders geometrically, the Total Surface Area is

2πrh + 2πr^2

r = radius of post = 0.5 feet

T. S. A =

2 x 3.14 x 0.5 x 7 + 2 x 3.14 x 0.5^2

= 23.55 sq ft.

Since there are 11 fence posts, the total surface area will be multiplied by 11

= 23.55 x 11 = 259.05 sq. ft.

Therefore, the quantity of paint will be equal to the total surface area of the fence posts.
