-7
Answer:
- x = 37
- DG = 22
- AG = 44
- AD = 66
Step-by-step explanation:
We presume your "centroid ratio theorem" tells you that AG = 2·DG, so ...
(x+7) = 2(x -15)
x + 7 = 2x - 30 . . . . eliminate parentheses
37 = x . . . . . . . . . . .add 30-x
Then AG = 37+7 = 44
and DG = 37-15 = 22.
Of course, AD = AG +GD = 44 +22 = 66

Answer:
Rate of increase in height =
Step-by-step explanation:
we know that volume of a cone is given by

It is Given that diameter equals height thus we have

Differentiating both sides with respect to time we get

Applying values and solving for
we get

7.96 / 6 = 1.33 <== unit rate
