Answer:
h=14.9966
Step-by-step explanation:
1. The formula of the volume is:
V=
2. So you have to substitute the the data that you have:
3533.5=
3. To have the area of the base (ab) you have to get the formula of the circle's area and solve:
A=()
A=()
A=3.1416(225)
A=706.86in
4. Now you have the area of the base:
3533.5=
5. In this step you are going to clear the variable which is the heigh (h) and solve as an equation:
3533.5=
3533.5(3)=706.86(h)
=h
h=14.9966
The result may vary depending on the value of that you use,
16 large candles and 12 small candles were sold.
Step-by-step explanation:
Given,
Worth of candles sold = $144
Total candles sold = 28
Cost of each large candle = $6
Cost of each small candle = $4
Let,
x be the number of large candles sold.
y be the number of small candles sold.
According to given statement;
x+y=28 Eqn 1
6x+4y=144 Eqn 2
Multiplying Eqn 1 by 4
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 2
Putting x=16 in Eqn 1
16 large candles and 12 small candles were sold.

Answer:
Step-by-step explanation:
Slope-intercept form is written in
So, to solve, we must separate y onto one side and make its coefficient one.
Subtract 4x on both sides.
Divide both sides by the coefficient of , which is 3.
Simplify.
Rewrite this equation into standard form by changing the order of and
Required: 10
8+5=13
How to get 10:
13-10=3
Therefore, in order to get 10 from the sum of 8+5, you must subtract 3.
Answer:
The cone has a larger volume.
Step-by-step explanation:
The volume of a cone is given by:
Where:
r: is the radius = 5 cm
: is the height of the cone = 10 cm
Then, the volume of a cone is:
Now, the volume of a pyramid is:
Where:
: is the area of the base
: is the height of the pyramid = 5 cm
The area of the base can be calculated as follows:
Hence, the volume of the pyramid is:
Therefore, the cone has a larger volume.
I hope it helps you!
