The surface area of a cylinder with circular bases of radius <em>r</em> and height <em>h</em> is equal to the sum of the areas of the two circular faces and the area of the rectangular lateral surface:
<em>A</em> = 2π<em>r</em>² + 2π<em>rh</em>
If you know the height <em>h</em>, then you can solve the quadratic equation for <em>r</em>.
X + y = 10
x - y = 2
add the equations together
2x = 12
x = 6
6 + y = 10
y = 3
Answer:
Use the given functions to set up and simplify:
F(−2) and that equals to 13
Step-by-step explanation:
So, therefore, your answer to the problem is 13.
Answer:
They do not equal eachother
Step-by-step explanation:
-4(2+9) + 3 = 6 - 4(-3)
-12 - 36 + 3 = 6 + 12
-45 = 18
So the lettuce went up by 0.25 or 25c, now, if we take 1.25 to be the 100%, how much is 0.25 in percentage off of it?
