Answer: The volume of the cone is 130 cubic centimeters.
Step-by-step explanation:
We know that to find the volume of a cylinder you will use the formula
V= 
Where r is the radius and h is the height.
And to find the volume of a cone you will use the formula
V= 
*h /3
So if they have the same dimensions which is the height and the radius then we will just divide the volume of the cylinder by 3 to find the volume of the cone.
V = 390/3
V = 130 cm^3
The answer is B. The actual reciprocal is 7/2, since the answer means isn't there its means the reciprocal of the negative or positive sign
Answer:
The value of the variable 'b' is 3 and GH is 9
Step-by-step explanation:
Given:

H is between G and I
Such that G - H - I
To Find:
GH = ?
Solution:
On Substituting HI we get

Substituting 'b' in HI and GI we get


Now, by Line Addition Property we get

Substituting 'HI' and 'GI' we get

The value of the variable 'b' is 3 and GH is 9
2x2-8x (two x squared minus 8 x)
