Answer:
The volume of cone A is twice the volume of cone B.
Step-by-step explanation:
The formula that is used to find the volume of a cone is given by :
Where
r is radius of cone and h is height
ATQ,
The radius of the base of cone A is twice as large as the radius of the base of cone B. The height of cone B is twice the height of cone A.
or
Taking ratios of their volume,
So,
The volume of cone A is twice the volume of cone B.

Answer:
Option B - 9 hours
Step-by-step explanation:
Given : Three machines operating independently, simultaneously, and at the same constant rate can fill a certain production order in 36 hours. If one additional machine were used under the same operating conditions.
To find : In how many fewer hours of simultaneous operation could the production order be filled?
Solution :
Let the numbers of hours taken including additional machine i.e. 4 machines be 'x' hours.
So, 3 machines take 36 hours
and 4 machines take x hours.
Then,
i.e. 4 machines spend 27 hours to do work.
Number of fewer hours of simultaneous operation could the production order be filled is given by,
hours
Therefore, the work could be done in 9 hours less.
So, the correct answer is B.
