Answer:
A
Step-by-step explanation:
To find surface area of a cylinder, find the 2 circles which is the formula a=pi(r)^2, when you get that, multiply that by 2 because both sides count. Than the middle which I would imagine like a soda can. Cut a line right down the middle and hen you take it out, it looks like a Rectangle. Find the circumvented of the circle which would be pi(d)=circumfrence. Now after that you found the top side now the other side is 12 as shown here on the model and multiply thm together you’ll get 84 pi. Now those 2 circles would add up to 32 pi. Add them together youll get 116 pi. Now pi could be any but I’d Use 3.14 which will get you about to A becuase after all 3.14 is an approximate.
Answer:
y = -30
Option A
Step-by-step explanation:
y = -2x - 10
y = -5x + 20
We just need to substitute the values of y.
We have to equate both the equation.
-2x -10 = -5x + 20
-2x + 5x = 20 + 10
3x = 30
x = 10
Plug x as 10 in any one of the equation
Let's take the first equation
y = -2x - 10
y = -2(10) - 10
y = -20 -10
y = -30
The answer is 200, if it’s wrong I’m sorry
The correct answer is <u><em>3*4=12/6=2+2=4</em></u>
<u><em>Your answer is 4</em></u>
