<h3>What is a cylinder?</h3>

A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.

Ellis is painting wooden fenceposts before putting them in his yard. They are each 6 feet tall and have a diameter of 1 foot. There are 12 fenceposts in all.

The amount of the paint that Ellis needs to paint all the surfaces of the 12 fenceposts will be

The area of the one fence post will be

Area = πdh

Area = 3.14 x 1 x 6

Area = 18.84 square feet

Then the paint for 12 fence posts will be

Total area = 12 x 18.84

Total area = 226.08 square feet

More about the cylinder link is given below.

A polygon has an interior angle sum of 9000. How many sides does it have
SSSSS [86.1K]

Answer:

52

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here the sum = 9000°, thus

180° (n - 2) = 9000° ( divide both sides by 180° )

n - 2 = 50 ( add 2 to both sides )

n = 52

How will you find the distance between these two points using Pythagorean theorem?
kow [346]
R represents radius or the distance between two points, the pythagorean expression will be
r² = Δx² + Δy²
Δ means the change, Δx means the change of x, Δy means the change of y

Given:
(x₁,y₁) = (-5,-1)
(x₂,y₂) = (0,2)

Input the numbers to the expression
r² = Δx² + Δy²
r² = (x₂ - x₁)² + (y₂ - y₁)²
r² = (0 + 5)² + (2 + 1)²
r² = 5² + 3²
r² = 25 + 9
r² = 34
r = √34

The distance is √34 unit length
