Answer:
It is given that the volume of a cone = 
cubic units
Volume of cone with radius 'r' and height 'h' = 
Equating the given volumes, we get
=
It is given that the height is 'x' units.
Therefore, 
Therefore, r = 3x
So, the expression '3x' represents the radius of the cone's base in units.

Well if you get back to the definition of a division, diving X by Y is finding out how many Ys you can have in a X.
It is clear that you will have more than X times Y if Y is less than 1 since dividing X by 1 is exactly X.
If you think of 10 and 1, you can divide 10 in exactly 10 portions of 1.
But you can divide it into 100 portions of 0,1.
And 100 is bigger than 10 of course.
Hope this helps.
Answer:
42
Step-by-step explanation:
The permutation formula is P(n, r) = n! / (n - r)!. We know that n = 7 and r = 2 so we can write:
7! / (7 - 2)!
= 7! / 5!
= 7 * 6 * 5 * 4 * 3 * 2 * 1 / 5 * 4 * 3 * 2 * 1
= 7 * 6 (5 * 4 * 3 * 2 * 1 cancels out)
= 42
