A cylinder with height of 4 meters has a volume of 2,827.43 cubic meters. Find the length of the diameter.
Answer: 30 meters
Step-by-step explanation:
Volume of a cylinder = πr^2h
2,827.43 = πr^2(4)
2,827.43 = 3.14(4)r^2
2,827.43 = 12.56*r^2
2,827.43/12.56 = (12.56*r^2)/12.56
225.11 = r^2, find square root of both sides
r = 15
diameter = 30
x2 + 4
Select all that apply
Answer:
The first three depending on what the first one says. 2 and three are definitely correct though. If the first one says x to the second power added by 4 then it is correct.

EGF?
32.8°
40.2
OOO
49.8°
57.2
Answer:
The answer is "[tex]40.2^{\circ}[/tex]"
Step-by-step explanation:
Please find the graph file.
Let
[tex]\angle EGF = x\\\\\sin x = \frac{12}{18.6}\\\\\sin x = 0.6452 \\\\x = \sin^{-1} (0.64516129) \\\\x = 40.1777695^{\circ} \approx 40.2^{\circ}[/tex]
A floor mat for gymnastics is a square with a side length of 14m. What is the area of the floor mat in square metres? Explain?
Answer:
196 square meters
Step-by-step explanation:
If the floor mat is square and one side is 14m then all sides are 14m. Given this you would find area by multiplying length by width.
L=14 W=14
14x14=196
There are 196 square meters
Find the area of the SHADED region.
Round to the nearest TENTH if necessary.
Answer:
112
Step-by-step explanation:
18×8= 144 for the area of the entire rectangle.
4×4= 16/2=8 for the area of the triangle.
8×4=32 because there are 4 triangles.
144-32=112 because you don't want the area of the triangles only the shaded area

Mary made 12 bracelets. 9 of those bracelets are the color blue.
What percent of bracelets are blue?
Answer:
75%
Step-by-step explanation:
We know that Mary made twelve bracelets and also that nine of them are blue, we are then asked to find the percentage of the bracelets that are blue.
To solve, first get a fraction of how many of the bracelets are blue. Since there are twelve in total, 12 will be our denominator, and since 9 are blue, 9 will be our numerator.
[tex]\frac{9}{12}[/tex]
Now to turn this into a percentage, we need to reduce this fraction to the lowest we can. Both numerator and denominator are divisible by 3, so do as followed :
[tex]\frac{9/3}{12/3}[/tex]
[tex]\frac{3}{4}[/tex]
Divide 3 by 4 :
[tex]3/4 = 0.75[/tex]
Multiply 0.75 by 100 to get our percentage :
[tex]0.75 * 100 = 75[/tex]%

If a fair die is rolled 6 times, what is the probability, to the nearest thousandth, of
getting exactly 2 threes?
Answer:
The probability of rolling the die once to get a four is 1/6
Step-by-step explanation:
So we do 1/6*1/6*1/6 which is 1/216 since it's combined probabilities

A cylindrical soup can has a diameter of 3.8 in. and is 5.4 in. tall. Find the volume of the can.
Answer:
the volume of the can is 61.21 cubic inches
Step-by-step explanation:
Given that
The diameter is 3.8 inches so the radius would be = 3.8 ÷ 2 = 1.9 inches
And, the height of the cylindrical soup is 5.4 inches
We need to find out the volume of the can
As we know that
The volume of the can is
[tex]Volume = \pi r^2h\\\\Volume = 3.14 \times 1.9^2 \times 5.4[/tex]
Volume = 61.21 cubic inches
Hence, the volume of the can is 61.21 cubic inches
We have a population of 200 people with a growth rate of 2%. Which equation do we use to calculate how long it will take for the population to double to 400 people? 70/.2 200/,2 200x2 400/2 70/2 70/.02 200/.02 200x.02 200/2
Answer:
70/2
Step-by-step explanation:
We have a population of 200 people
Growth rate = 2%
How long it will take for the population to double
Double the population = 2× 200 = 400
The formula for Exponential growth =
y = a(1 + r)^t
y = Value at time t = 400
a = Initial value = 200
r = 2% = 0.02
t = ?
Hence:
400 = 200 ( 1 + 0.02)^t
Divide both sides by 200
400/200 = 200 ( 1 + 0.02)^t/200
2 = (1.02)^t
Take logarithm of both sides
log 2 = log(1.02)^t
log 2 = t log 1.02
t = log 2/log 1.02
t = 35.003417942
Approximately t = 35
We have so many formula to calculate doubling time
t = 70/Growth rate
From the above question
Growth rate = 70/2%
= 35
Therefore, the equation that we use to calculate how long it will take for the population to double to 400 people is 70/2

You choose two different movies on a list at random. Out of 10 movies on the list, 6 are action movies. The first movie you choose is an action movie. What is the probability that the second movie is also an action movie? Write your answer as a fraction in simplest form.
Answer:
5/9
Step-by-step explanation:
You have 10 movies in total. You take 1 out of 6 action movies. Now you have 5 action movies left, so that means the probability is 5/9. It's 5/9 because you chose 1 action movie out of 10 movies in total, so that means there are 9 movies in total left.
