Answer:
301.44
Step-by-step explanation:
Equation for the volume of a cone: V = π
Here, r = 6 and h = 8.
V = π
V = 3.14 * 
* 
V = 3.14 * 36 *
V = 301.44
Or, in exact terms of π, 96π.
8 times 8 is the closest you can get to 71 without going over, since 8 times 9 would be 72.
The amount of cloth needed to make 1 headband is 10 meters.
<h3>Unit value</h3>
- Number of headbands Anne made = 6
- Total clothes used = 3/5 meters
Cloth needed to make 1 headband = Number of headbands Anne made / Total clothes used
= 6 ÷ 3/5
= 6 × 5/3
= (6 × 5) / 3
= 30/3
= 10 meters
Therefore, the amount of cloth needed to make 1 headband is 10 meters.

Look at the image down below!!
Answer:
x = -8
Y = -11
Step-by-step explanation:
Given
Y = 3x + 13
Y = x - 3
Substitute x - 3 for Y in the first equation
We have
Y = 3x + 13
x - 3 = 3x + 13
Add 3 to both sides
x - 3 + 3 = 3x + 13 + 3
x = 3x + 16
Subtract 3x from both sides
x - 3x = 3x - 3x + 16
-2x = 16
Divide both sides by -2
x = 16/-2
x = -8
Now substitute -8 for x in any of the above equations to get Y.
Using the second equation, we have
Y = x - 3
Y = -8 - 3
Y = -11
