The formula for volume of a cylinder is pi*r^2*h
So reversing that,
Volume/height/pi =
54/6/3.14 = <span>2.86624203822 or 2.9 </span>
Answer:
The number w is 4,000
Step-by-step explanation:
Let
w ------> the number
we know that
36 is 0.9% of number w
w represent the 100%
so
using proportion
Find out the number w
therefore
The number w is 4,000
Answer:
The volume of a cone is 1/3 of the volume of the cylinder.
Step-by-step explanation:
The formula for a cylinder is:
V = bh
For a cone:
V = 1/3(bh)
If the radius of both are the same, then the area of the base is the same. The height is also constant, therefore:
The volume of a cone is 1/3 the volume of the cylinder.
--------------------------
Example to prove:
Given, radius 2 and height 15:
Cylinder: V = bh (b = πr²)
V = 4π × 15
V = 60π u³
Cone: V = 1/3 (bh)
V = 1/3 (4π × 15)
V = 20π u³
Answer:
3.600
Step-by-step explanation:
0.25(x+1.6)+5x=18
Open the bracket first
0.25x+0.72+5x=18
Collect like terms
0.25x+5x=18-0.72
5.25x=18.72
Divide both sides by 5.25
x=3.566~3.600(nearest hundredth)
