Cylinder radius is 2 cm height is 10cm what is the surface area
Answers
Given:
Radius of a cylinder = 2 cm
Height of the cylinder = 10 cm
To find:
The surface area of the cylinder.
Solution:
The total surface area of the cylinder is:
[tex]A=2\pi rh+2\pi r^2[/tex]
Where, r is the radius and h is the height of the cylinder.
Putting [tex]r=2[/tex] and [tex]h=10[/tex] in the above formula, we get
[tex]A=2\pi (2)(10)+2\pi (2)^2[/tex]
[tex]A=40\pi +2\pi (4)[/tex]
[tex]A=40\pi +8\pi [/tex]
[tex]A=48\pi [/tex]
Therefore, the surface area of the cylinder is [tex]48\pi [/tex] square cm and its approximate value is 150.8 square cm.

If g(x)= x+2/x-2 and h(x) = 4 - X, what is the value of (GoH)(-3)?
A.) 8/5
B.) 5/2
C.) 15/2
D.)18/5
Answers
Answer:
A. 8/5
Step-by-step explanation:
please be careful when typing the question. you made a mistake here (you wrote "x+2" instead of "x+1"). luckily you have provided also the screen shot.
the used symbolism of a composite function is nothing else than asking for
g(h(x)) for x=-3.
so, first we need to calculate h(-3) = 4 - -3 = 7
then we take that result as argument for g : g(7) = 8/5
so, altogether
g(h(-3)) = g(7) = 8/5
we can do this generically for x by substituting x in g by the expression of h
g(h(x)) = ((4-x) + 1) / ((4-x) - 2) = (5-x)/(2-x)
for x = -3 this gives (5- -3)/(2- -3) = 8/5
The value of the composite function (g o h) (-3) is 9/5.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
First, we need to find the composition g o h, which means we need to substitute h(x) into g(x), so that:
(g o h)(x)
= g(h(x))
= g(4 - x)
= [(4 - x) + 2] / [(4 - x) - 2]
= (6 - x) / (2 - x)
Now, we can find (g o h)(-3) by substituting x = -3 into the expression above, which gives:
(g o h)(-3)
= (6 - (-3)) / (2 - (-3))
= 9 / 5
Therefore,
The value of (g o h)(-3) is 9/5.

Find the value of A
Answers
Answer:
a = 5
Step-by-step explanation:
Angles A and B are the same at 45, a and b are also the same
The law of sines is based on the proportionality of sides and angles in triangles. The law states that for the angles of a non-right triangle, each angle of the triangle has the same ratio of angle measure to sine value.
sin(A)/a = sin(B)/b = sin(C)/c
Substitute the known values into the law of sines to find a.
SinA / a = sin(90) / 5√2
a = 5

Step-by-step explanation:
a). 840 miles
350 miles ÷ 25 gallons = 14
14 (miles per gallon) x 60 gallons of gas = 840
b). 14
(first step of the first answer)
350 miles ÷ 25 gallons = 14 miles per gallon
hope this helped!
a) 840 miles can go for 60 gallons of gas.
b) The mileage is 14 miles per gallon.
Here, we have,
given that,
A new truck can travel 350 miles on 25 gallons of gas.
now, we have,
a). we get,
the milage of the truck is:
350 miles ÷ 25 gallons = 14
so, we get,
for 60 gallons of gas it can go:
14 (miles per gallon) x 60 gallons of gas = 840
so, 840 miles can go for 60 gallons of gas.
b). and, again we have,
the milage of the truck is:
(first step of the first answer)
350 miles ÷ 25 gallons = 14 miles per gallon
