A cylinder has a volume of 371.776 cubic centimeters. The diameter of the cylinder is 8 cm. What is the height of the cylinder? (Assume = 3.14)
Cylinder volume formula:
V=πr^2h
Substitute given values into the formula
Note: use 3.14 for pi
Diameter is twice the radius, so if diameter is 8 then radius is 4
371.776 = (3.14)(4^2)h
Use h for height because we don't know the height
Okay, so let's try to get the h by itself on the left side of the equation
So begin by getting rid of 3.14 by dividing it by both sides
371.776/3.14 = 118.4
3.14/3.14 = 1 (don't put 1, just remove the 3.14 from the right side)
So now we have:
118.4 = 4^2(h)
Now we can get rid of 4^2
Start by actually squaring it and then divide it from both sides
118.4 = 16(h) (4^2 = 16)
118.4/16 = 7.4
16/16 = 1 (dont put 1, just drop it)
So now we have
7.4 = h
Now we have h by itself! So h = 7.4
let's test it by putting it in the cylinder volume formula
V = πr^2h
371.776 = (3.14)(4^2)(7.4)
371.776 = (3.14)(16)(7.4)
371.776 = 50.24(7.4)
371.776 = 371.776
7.4 is your answer, if you have any questions, feel free to ask

Answer:
$13.35
Step-by-step explanation:
To find the amount of discount, multiply the discount rate by the usual price of the small TV.
discount rate * regular price
The discount rate is 15% and the regular price of the small TV is $89.00
15%*$89.00
15%*89
Convert 15% to a decimal by dividing 15 by 100, or moving the decimal place two spots to the left.
15/100=0.15
15.0-->1.5-->0.15
0.15*89
Multiply
13.35
The discount amount is $13.35
So the amount of discount is $13.35

The angular velocity of a fan blade is 6.2 radians per second.
Approximately how many revolutions does the fan blade make in 1.6 minutes?
Enter your answer, rounded to the nearest tenth of a revolution
Answer:
94.7 revolutions
Step-by-step explanation:
In the question above, we are given the following values for the fan
Angular velocity = 6.2 radians per seconds
Time = 1.6 minutes.
Step 1
We would convert the time given to seconds
1 minute = 60 seconds
1.6 minutes = ?
We cross multiply
1.6 minutes × 60 seconds
= 96 seconds
Step 2
Number of revolutions made by the fan is calculated as :
Angular velocity(rad/s)
× time(seconds)
Number of revolutions = 6.2 radians per seconds × 96 seconds
=595.2 radians
Converting from radians to revolution
1 radian = 0.159155 revolutions
595.2 radians =
Cross multiply
= 595.2 radians × 0.159155 revolutions
= 94.729056 revolutions.
Approximately to the nearest tenth = 94.7 revolutions.
Therefore, the number of revolutions the fan blade makes in 1.6 minutes is 94.7 revolutions.
1.6 minutes is 1.6 x 60 = 96 seconds.
Its angular velocity is 6.2 radians per second: 6.2 radians/second x 96 seconds = 595.2 radians.
One revolution of the fan is one circumference of the fan, which is 2pi radians.
Dividing 595.2 radians by 2pi radians gives us an answer of 94.7 revolutions.

The half-life of a certain radioactive material is 37 days. An initial amount of the material has
a mass of 477 kg. Write an exponential function that models the decay of this material. Find
how much radioactive material remains after 6 days. Round your answer to the nearest
thousandth.
Answer is option B that ends with 426.288 kg.
The exponential function that models the decay of this material is [tex]477(\frac{1}{2})^{(\frac{t}{37} )}[/tex] and the quantity of substance remains is 426.28 grams
What is Half life?Half-life, in radioactivity, the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay.
What is Radioactive material?Radionuclides (or radioactive materials) are a class of chemicals where the nucleus of the atom is unstable
Given,
Half life of a certain radioactive material = 37 days
Initial amount of the material = 477 grams
Quantity of substance remains N(t) = [tex]N_{0}(\frac{1}{2})^{(\frac{t}{half-life} )}[/tex]
Substitute the value in the equation N(t) =[tex]477(\frac{1}{2})^{(\frac{t}{37} )}[/tex]
[tex]477(\frac{1}{2})^{(\frac{t}{37} )}[/tex] is the exponential function that models the decay of this material.
Quantity of substance remains after 6 days = [tex]477(\frac{1}{2})^{(\frac{6}{37} )}[/tex] = 426.28 grams
Hence, the exponential function that models the decay of this material is [tex]477(\frac{1}{2})^{(\frac{t}{37} )}[/tex] and Quantity of substance remains is 426.28 grams
