A cone has a diameter of 12 centimeters and a height of 9 centimeters. Using 3.14 for pi, find the
volume of the cone to the nearest tenth.
Answers
A cone has a diameter of 12 centimeters and a height of 9 centimeters. The volume of the cone would be 2034.72 cubic cm.
How to find the volume of a right circular cone?
Suppose that the radius of considered right circular cone be 'r' units.
And let its height be 'h' units.
Then, its volume is given as:
[tex]V = \dfrac{1}{3} \pi r^3 h \: \rm unit^3[/tex]
The right circular cone is the cone in which the line joining the peak of the cone to the center of the base of the circle is perpendicular to the surface of its base.
A cone has a diameter of 12 centimeters and a height of 9 centimeters.
Radius = 12/2 = 6cm
Height h = 9 cm
The volume of the cone
[tex]V = \dfrac{1}{3} \pi r^3 h \: \rm unit^3[/tex]
[tex]V = \dfrac{1}{3} \times 3.14 \times 6^3 \times 9\: \rm unit^3\\\\V = 3.14 \times 648\\\\V = 2034.72 cm^{3}[/tex]
Hence, The volume of the cone would be 2034.72 cubic cm.

Emily has 6 gallons of water josh has 23 quarts of water. How many more points does Emily have more than josh
Answers
Answer:
2 pints
Step-by-step explanation:
To determine the amount of pints that Emily has more than Josh, gallons and quarts have to be converted to pints and the value is then subtracted
1. Convert gallons and quarts to pints
1 gallon = 8 pints
6 gallons = 8 x 6 = 48 pints
1 quart = 2 pints
23 quarts = 2 x 23 = 46 pints
2. Determine the difference in the amount of pints Emily has and the amount Josh has
48 pints - 46 pints = 2 pints

Pinz
Step-by-step explanation:
So to set up the equation for Lanez:
y = 3.5 + 4.25x
Next we compare the prices for both overall by plugging 6 games in as x:
Lanez:
y = 3.5 + 4.25(6)
y = 3.5 + 25.5
y = 29
Pinz:
y = 3.75 + 4(6)
y = 3.75 + 24
y = 27.75
29>27.75
Lanez is more expensive with it costing $29 for a night as opposed to the $27.75 one would pay to play at Pinz.

Answers
Answer:
0=0 or as known as infinite solution
Step-by-step explanation:
when answering a type of question there are 3 steps
1) Distribute: 3(6x+8)=24+18x
3 x 6x= 18x 3 x 8= 24
18x +24 = 24 + 18x
2) Subtract 24 from both sides of the equation:
18x + 24 = 24 + 18x
-24 -24
18x + 0 = 0 + 18x
3) Subtract 18x from both sides to set apart (x) : 18x = 18x
-18x -18x = 0 = 0

Use the table and graph to show what the fine will be, and how much Ali will have saved, after each month. How long will it take to pay off the ticket, and how much will it end up costing in total?

solve for x
solve for x
Answers
Answer:
121
Step-by-step explanation:
Number of sides = n = 7
Sum of all the interior angles = (n -2)*180 = (7-2) *180
= 5 *180
= 900
x + 125 + 119 +117 +145 + 133 + 140 = 900
x + 779 = 900
x = 900 - 779
x = 121
Answer:
x = 121°
Step-by-step explanation:
The formula to find the sum of interior angles of a polygon is:
180 ( n - 2 )
Here,
n ⇒ number of sides ⇒ 7
First, let us find the sum of the interior angles of the polygon.
180 ( n - 2 )
180 × ( 7 - 2 )
180 × 5
900°.
Accordingly, let us make an expression to find the value of x.
145 + 133 + 140 + 125 + 119 + 117 + x = 900
Let us solve for x now.
779 + x = 900
Subtract 779 from both sides.
x = 900 - 779
x = 121
