Answer:X= 19/2
Step-by-step explanation:
Answer:
The answer is 9
Step-by-step explanation:
take 4 to the other hand it become -4
r=13-4=9
Assuming the cylinder is closed at both ends
Surface area = 2 pi r^2 + 2 pi r h = 108
now h = r/2 so we have:-
2pi r^2 + pi r^2= 108
3 pi r^2 = 108
r^2 = 11.459
r = 3.385
so the height h = 1.693 m to nearest thousandth
By the binomial theorem, the 
term in the expansion of 
is
which suggests that the contribution of the binomial coefficient should make up the remaining factor of 21. That is,
All of them Are correct, assuming this is the recipe.
