There is not enough information to answer the question as it is stated. If the value of pi*r2*h/3 is known (to be k, say) then h = 3*k/(pi*r2)
If h = 7 then h squared = 49
It depends on the exact value of h, but, algebraically, the answer is h/24.

When h has the value of 4, you substitute 4 for h in the expression 16-3h. This gives you 16 - 3(4), which simplifies to 16 - 12. Finally, the answer is 4.

The expression h + 56 can't be simplified. If you assign a value to h, you can calculate the sum.
It is: (5*12)-2 = 58
There is not enough information to answer the question as it is stated. If the value of pi*r2*h/3 is known (to be k, say) then h = 3*k/(pi*r2)
To calcualte NCV you need calorific value on GAR, H on gar and Total moisture.
If you mean: 6h+7 then 6*5 plus 7 = 37
"First principles" in this context means that you:* Calculate the value of the function, at some point "x+h" * Calculate the value of the function, at some point "x" * Subtract the first result minus the second result * Divide all this by "h" * See what happens when you make "h" smaller and smaller (when it tends to zero) As a formula: F(x)' = lim (as h --> 0) [F(x+h) - F(x)] / h
Cn H 2n + 2 If you have C3 then n equals 3 n=3 C3 H 2 X 3 + 2 = 8 so H equals 8 thats why you have C3H8 and this is propane
