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
What? This isn’t a question
Answer:
66 = s
Step-by-step explanation:
s + 24 = 90
90 = s + 24
90 - 24 = s
66 = s
R = l + (3w)/2
Subtract 'l' to both sides:
r - l = (3w)/2
Multiply 2 to both sides:
2r - 2l = 3w
Divide 3 to both sides:
w = (2r - 2l)/3
