Ellis is painting wooden fenceposts before putting them in his yard. They are each 5 feet tall and have a diameter of 1 foot. Th
maksim [4K]

Answer:

Step-by-step explanation:

Comment

The first step is to find the surface area of 1 fence post.

The formula is

Area_ends = 2 pi r^2 for the ends.

Area_body = 2*pi*r * h

Givens

r = d/2          r is the radius ; d is the diameter

r = 1/2 foot

h = 10 feet

Solution

1 fence post

Area = ends + area body

Area =  2*3.14 * (1/2)^2 + 2 * pi * r * h

Area = 2*3.14* (1/2)^2 + 2 * 3.14 * 1/2 * 10

Area = 1.57 + 31.4

Area = 32,97 square feet.

10 fence posts

10*32.97 = 329.7 square feet

Answer

10 fence posts have 329.7 square feet in area.

Find the equation of the line that passes through (3,-2) and whose m=1/2
Oxana [17]

y=m x+c

If m=\frac{1}{2}

Then:

y=\frac{1}{2} x+c

Sub in the coordinates given to you:

-2=\frac{1}{2} *3+c

Now:

\frac{1}{2}*3=1.5

Move 1.5 to the other side of the equation and flip the sign.

-2-1.5=c

Therefore, c = -3.5.

Replace in the formula (y=mx+c):

y=\frac{1}{2}x-3.5

There is your answer.
