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
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
-0.8 mhm :)
how: u add them all up n then divide by how many numbers there are !! in this case: 2+2+-2+-4+-3+0 = -5 and there’s 6 numbers and then 5/6 is .83 repeated but u just round to .8 because, “four or less, give it a rest ... five or more raise the score!” that’s how i remember :) i already saw an answer for this but i decided to explain anyways in case u didn’t understand. have a great day<3

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>
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.
