Surface Area of Cylinder
The circumference of the base is 5.7
Step-by-step explanation:
The lateral surface of an object is defined as the area of all the sides of the object, excluding the area of its base and top.
A cylinder has two faces, two curved edges where the curved wall meets the end circles, and a curved surface stretching between the two circular ends.
For a cylinder, the lateral surface area is the curved surface that connects the base and the top.
The lateral surface area
where r is radius of the base of the cylinder
and h is height of the cylinder
and is 3.14
The circumference of the base of cylinder = C
where C =
Given = 34 and h = 6
⇒ = C × h
⇒
⇒ C = = 5.7
Hence the circumference of the base of the cylinder is 5.7
The discriminant is the bit under the radical, the .
Because it's under a radical, it's what tells you how many and what kind of solutions you have (two real, one real, or two imaginary/complex solutions).
Does that answer your question? Or do you need an example?
Suppose you had the equation , then you'd have:
, and
You'd plug those values into to see if the discriminant was positive, zero, or negative:
Since that is 37 (a postiive number), you'd have two real solutions.
the ratio of zinc to copper is 3 to 14, that menas that for each 3 grams of zinc there are 14 grams of copper, so we can made a rule of three to find
Answer:
0
Step-by-step explanation:
-5 + 7 - 6 - (-4)
-11 + 7 - (-4)
-11 + 7 +4
-11 + 11
= 0
