The volume of the cylinder in cubie centimeter is 628 [tex]cm^{3}[/tex]
How to find the volume of cylinder?
1. Find the radius of the circular base: Since both circles are the same size, either one will work. Move on if you are aware of the radius. If you don't know the radius, you can divide the diameter of the circle by 2.
2. Find the height of the cylinder : Continue if you already know the height. Otherwise, measure it with a ruler. The height is determined by the separation of the two bases' edges.
diameter (d) = 20
radius = [tex]\frac{20}{2}[/tex]
r = 10
height (h) = 2cm
volume v = [tex]\pi r^{2} h[/tex]
v = 3.14(10*10)2
= 628 [tex]cm^{3}[/tex]

Compute the probability of tossing a six sided die with sides numbered 1 through 6 and getting a 5
The probability of tossing a six-sided die with sides numbered 1 through 6 and getting a 5 is 0.166666 or 1/6.
Here in the question, we see that a six-sided die is tossed. So there will be a total of 6 outcomes.
So the sample space will be {1,2,3,4,5,6}
Of which the possible outcome of getting a 5 is 1
Let A be the event of getting a 5 on tossing a six-sided die
∴ the probability of getting a 5 on tossing a six-sided die is P(A)=1/6
∵ we know that the probability of an event is the possible outcome of the event divided by the total outcomes of that event.
So here the probability of getting a 5 is 0.166666 or 1/6.

The value of the function f(a+4) is [tex]\frac{7}{a^{2} +8a+11}[/tex]
What is a function?function, in mathematics, is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable called the dependent variable.
if f(x) = [tex]\frac{7}{x^{2} - 5}[/tex], which means this equation is a function of x,
To find another equation whose function is f(a + 4)
We substitute x for a + 4 in the above equation
