Answer:
18.85 inches³
Step-by-step explanation:
Given:
Height of the cylindrical glass, h = 8 inches
Diameter of the cylindrical glass = 2 inches
or
Radius of the cylindrical glass, r = 1 inches
Now,
the volume of the cylindrical glass = πr²h
or
the volume of the cylindrical glass = π × 1² × 8 = 8π inches³
therefore, the volume of tea in the cylindrical glass = 8π inches³
Now,
Lily drinks only 3/4 of her tea
therefore,
the volume of tea Lily drunk =
or
the volume of tea Lily drunk = 18.85 inches³
Answer:
C) The range is 70.
Step-by-step explanation:
How to find range:
Subtract the lowest value from the highest value and there's your answer
I think it is 9 Hope you got it.
It's important to do the same thing to both sides in an equation so it stays equal,
so first you group like terms (x with x and #'s with #'s)
so
2x+5x+3x+20=95+25
10x+20=120
subtract 20 from both sides
10x=100
divide both sides by 10
x=10
<span>The formula for the volume of a cylinder is V=πr²h. The volume of a cylinder is three times the volume of a cone with the same radius and height.
Now, volume of cone is 1/3</span>πh
<span>
If the volume of a cone with the same height as a cylinder equals the volume of a cylinder, the equation for the radius of cone in terms of the radius of cylinder R, is equal to 3R.
We get this by equating the volume of cone and cylinder:
