Ellis's painting wooden fence post before putting them in his yard there are each 5 feet tall and have a diameter of 1 foot there are 10 fence post to know how much paint will alice need to paint all the services of the 10 principles use 3.14 for pie and round your answer to the nearest hundred

the paint needed would cover 329.7 ft²

Step-by-step explanation:

We want to determine the amount of paint required to paint the total surface area of the 10 fence posts.

The fence posts are cylindrical.

The formula for determining the total surface area of a cylinder is expressed as

Total surface area = 2πr² + 2πrh

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

π is a constant whose value is 3.14

From the information given,

radius = diameter/2 = 1/2

r = 0.5 foot

h = 5 feet

Therefore, the total surface area of each fence post is

Area = (2 × 3.14 × 0.5²) + (2 × 3.14 × 5)

Area = 1.57 + 31.4 = 32.97 ft²

The total surface area of 10 fence posts would be

10 × 32.97 = 329.7 ft²
