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

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
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
