A cylinder has a radius of 40 ft and a height of 17 ft.
dusya [7]
So the formula is 2pi(r)(h)+2(pi)(r^2)

2(3.14)(40)(17)+2(pi)(40^2)
so then multiply and add it up and you get

about 14,325 1/3 or 14,325.34

The diagram shows a triangle.
nordsb [41]

Answer:

A = 110.25

Step-by-step explanation:

add all the equations and equal it to 180 because all triangle angles add to 180:

4x+1 + 3x + 3x-1 = 180

10x =70

/10   /10

x = 7

Insert x into each equation and solve:

3(7)-1 = 20

4(7)-1 = 27

3(7) = 21

and then use A = 1/2 base*height formula:

A= 1/2 21* 20

A= 210

Solve the system using substitution. -x+y=9 and x-y=-9
Elina [12.6K]

Answer:

Infinite Number of Solutions

Step-by-step explanation:

Hello!

We can solve for y in the first equation, and plug that value in for y in the second equation.

<h3>Find the Equation for Y</h3>
  • -x + y = 9
  • y = 9 + x

Now that we know the equation for y, we can plug that in for y into the second equation to solve for x.

<h3>Solve for X</h3>
  • x - y = -9
  • x - (9 + x) = -9
  • x - 9 - x = -9
  • -9 = -9

Since the equations match, there are an infinite number of solutions.

If we take a close look at the equations, we can also see that they are the same equation, but with flipped signs.
