The diameter of a circle is 6 centimeters. What is the circle's area?
Use 3.14 for pi
Step-by-step explanation:
diameter=
[tex]2 \times\pi \times r = 6 \\ r = \frac{6}{2 \times 3.14} = 0.955 \\ area = \pi \times {r}^{2} = 3.14 \times {0.955}^{2} \\ = 2.87\: {cm}^{2} [/tex]
1. Could you use an inscribed prism to derive the volume of a hemisphere? Why or why not? Are there any other ways you could approximate a hemisphere, and what problems would you encounter in finding its volume?
2.Could you use a circumscribed regular n-gon as the base of a pyramid to derive the formula for the volume of a cone? Explain.
We can always get the volume of the figure whenever we get enough data to recreate that considered figure, because it provides us with necessary measurements needed for finding the volume.
When can we find the volume of a considered figure?For finding volume of the considered figure, we somehow needs measurement of its correct dimensions by which we would be able to recreate the figure. By any means, if we could get enough measurement, then we'd be able to characterize the figure, and thus, get its volume.
Case 1. Could you use an inscribed prism to derive the volume of a hemisphere? Why or why not? Are there any other ways you could approximate a hemisphere, and what problems would you encounter in finding its volume?
Yes, if the prism fits perfectly, and we know about the prism, then it would tell us about the radius of the hemisphere. For example, we can fit a cubic prism inside it, and diagonal of that cube's base will give diameter of that hemisphere.
Case 2.Could you use a circumscribed regular n-gon as the base of a pyramid to derive the formula for the volume of a cone?
Yes, because the the base of the pyramid can give the details about radius of the cone's base, and due to the n-gon being regular and circumscribed, the height of the cone would be same as that of the height of that n-gon.
Thus, we can always get the volume of the figure whenever we get enough data to recreate that considered figure, because it provides us with necessary measurements needed for finding the volume.

If 0 < b ≤ 90 and cos(11b + 2) = sin(12b − 4), what is the value of b? b = 3 b = 4 b = 5 b = 6
Answer:
[tex]b = 6[/tex]
Step-by-step explanation:
Given
[tex]0<b\le 90[/tex]
[tex]\cos(11b + 2) = \sin(12b - 4)[/tex]
Required
Find b
To solve this, we make use of the following trigonometry rule:
If [tex]\cos(\alpha) = \sin(\beta)[/tex]
Then: [tex]\alpha + \beta = 90[/tex]
So:
[tex]11b + 2 = 12b - 4[/tex]
Collect like terms
[tex]11b - 12b = - 4 - 2[/tex]
[tex]-b = - 6[/tex]
Multiply both sides by -1
[tex]b = 6[/tex]

17Step-by-step explanation:
We can find the longest side I.e. Hypotenuse using pythogorean theorem.
[tex] {8}^{2} + {15}^{2} = {x}^{2} \\ 64 + 225 = {x}^{2} \\ 289 = {x}^{2} \\ x = \sqrt{289} \\ x = 17[/tex]
This is your answer hope it helps :)
Answer:

Step-by-step explanation:
a squared + b squared = c squared (hypothenuse longest side)
square them, then add them and square root them.
What are the 3 steps to solving an inequality?

Do you know how to use the formulas?

series? What is the difference between the two?
Do you know to use the formulas?
What is the difference between arithmetic and geometric?
Do you know how to find the average rate of change?
What is sigma notation? What are the parts?
What does it mean for a graph to be discrete? Continuous?
Answer:
down here. I dont expect you to copy paste
Step-by-step explanation:
Arithmetic sequence: An arithmetic sequence is a sequence where each term increases by adding/subtracting some constant k.
Arithmetic series : An arithmetic series is the sum of a sequence in which each term is computed from the previous one by adding (or subtracting) a constant
Difference: A sequence is defined as an arrangement of numbers in a particular order. On the other hand, a series is defined as the sum of the elements of a sequence.
How to use them : maybe
Geometric Sequence : A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.
Geometric series : In mathematics, a geometric series is the sum of an infinite number of terms that have a constant ratio between successive terms.
Difference: A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.In mathematics, a geometric series is the sum of an infinite number of terms that have a constant ratio between successive terms.
How to use: maybe
Arithmetic and geometric difference: The main difference between arithmetic and geometric sequence is that arithmetic sequence is a sequence where the difference between two consecutive terms is constant while a geometric sequence is a sequence where the ratio between two consecutive terms is constant.
Average rate of change : To find the average rate of change, we divide the change in the output value by the change in the input value.
Sigma notation :Often mathematical formulae require the addition of many variables Summation or sigma notation is a convenient and simple form of shorthand used to give a concise expression for a sum of the values of a variable.
Graph: A continuous function allows the x-values to be ANY points in the interval, including fractions, decimals, and irrational values. A discrete function allows the x-values to be only certain points in the interval, usually only integers or whole numbers.

Answer:
c
Step-by-step explanation:
The formula that should be set up correctly to help him do this should be considered as the [tex]400(1 + 5.5\%)^{60}[/tex]
Calculation of the formula:Since
the invested amount is $400
The annual compound interest is 5.5%
