A cone has a volume of 640.56 cubic feet and a height of 17 feet. What is its radius?
Use ≈ 3.14 and round your answer to the nearest hundredth.
V=640.56
H=17 ft
what is it's radius though?
Answer:
6
Step-by-step explanation:
Cone volume : V = pi r² . h/3
radius = sqrt ((3V) / (pi.h))
radius = sqrt ((3 x 640.56) / (17 x 3.14))
radius = sqrt ( 1921.68 / 53.38 )
radius = sqrt ( 36 )
radius = 6

Answer:
x = 11
Step-by-step explanation:
Given;
[tex]x-\frac{1}{x}=3[/tex]
Squaring equation;
[tex](x-\frac{1}{x})^2=3^2[/tex]
[tex]x^2+\frac{1}{x}^2-2*x*(\frac{1}{x})=9[/tex]
By algebraic identity :
[tex](a-b)^2=a^2+b^2-2ab[/tex]
Substitute
[tex]x^2+\frac{1}{x}^2 - 2 = 9[/tex]
Add
[tex]x^2 + \frac{1}{x}^2 = 9 +2[/tex]
Simplify
[tex]x^2 + \frac{1}{x}^2 = 11[/tex]
Hence, x = 11.

The temperature dropped - 16.8 degrees over the course of 5 days. What was
the average daily temperature change?
Add an explanation to this if possible, <3
Answer:
The average change would be -3.36 degrees.
Step-by-step explanation:
We take the overall temperature change which is -16.8 and we would just simply divide that by 5. That's all to get the temperature.
Another example would be if the temperature change was 16 over the course of 4 days. In this case we would take the overall (16) and divide that by the number of days. There would be an average of 4 degree temperature change.
Need help finding the slope and how to graph it.

#TheWizzer
Among all there is no condition which will not create a gap or an overlap at a vertex of polygon.
What is polygon?A polygon is a plane figure that is having finite number of sides which are connected to form a closed figure.
How to determine angle?In this we have two cases:
case 1: If the polygons are regular.
The sum of all the angles is equal to 360°.
For example: Consider a quadrilateral polygon whose four sides are congruent and each angle is 90°. Then the sum of angles is 90+90+90+90=360°.
case 2: If the polygons are not regular
We know that sum of angles can be found by (n-2)*180°
Suppose polygon is 3 sided so the sum will be (3-2)*180=180° which is less than 360°.
Suppose polygon is 6 sided so the sum will be (6-2)*180°=720° which is greater than 360°.
Hence there is no condition which will not create a gap or an overlap at a vertex of polygons.

Finding the areas of each of the rectangles and squares of the net of a rectangular prism and adding up those areas gives the surface area or total surface area of the prism. For example, if the length of one side of the cube 4 units then the area of one its face is 4 × 4 = 16 square units.
Complete question is;
Finding the areas of each of the rectangles and squares of the net of a rectangular prism and adding up those areas gives the surface area or total surface area of the prism. For example, if the length of one side of the cube 4 units then the area of one its face is 4 × 4 = 16 square units. From the net, we can see that there are six equal faces and so we get the total surface area is 6 × 16 = 96 square units.
Find the total surface area of the rectangular prism attached.
Answer:
72 cm²
Step-by-step explanation:
From the rectangular prism attached, we can see that it has 6 sides.
Now, each side has a mirrored part which is of same dimensions with it.
Thus, unfolding to get a net, we have;
2 faces with dimension: 3cm × 6cm
2 faces with dimension: 2cm × 6 cm
2 faces with dimension: 2cm × 3cm
Thus,total surface area is;
2(3cm × 6cm) + 2(2cm × 6cm) + 2(2cm × 3cm) = 36 + 24 + 12 = 72 cm²

Find the measures of the complementary angles that satisfy each case.
The measure of the first angle is 40° less than the measure of the second.
Answer: x+(x+40)=90
PLS SHOW UR WORK. IF U ARE ABLE TO, DO A STATEMENT AND REASONING.
Given:
The measure of the first angle is 40° less than the measure of the second.
To find:
The measures of the complementary angles that satisfy the given condition.
Solution:
Let the measure of first angle be x°.
According to the given condition,
First angle = Second angle - 40°
[tex]x^\circ =\text{Second angle}-40^\circ [/tex]
Add 40° on both sides.
[tex](x+40)^\circ =\text{Second angle}[/tex]
We know that, sum of complementary angles is 90°. So,
First angle + Second angle = 90°
[tex]x^\circ +(x+40)^\circ =90^\circ [/tex]
[tex]2x^\circ +40^\circ =90^\circ [/tex]
[tex]2x^\circ =90^\circ -40^\circ [/tex]
[tex]2x^\circ =50^\circ [/tex]
Divide both sides by 2.
[tex]x^\circ =25^\circ [/tex]
So, the measure of first angle is 25°.
[tex](x+40)^\circ =(25+40)^\circ =65^\circ[/tex]
So, the measure of second angle is 65°.
