Answer:
Volume of this cylinder = 785.71 Cm³
Surface area of this cylinder = 157.14 Cm²
Step-by-step explanation:
Given:
Height of cylinder = 10 Cm
Radius of cylinder = 10 / 2 = 5 Cm
Find:
Volume of this cylinder.
Surface area of this cylinder
Computation:
Volume of this cylinder = πr²h
Volume of this cylinder = (22/7)(5)²(10)
Volume of this cylinder = 785.71 Cm³
Surface area of this cylinder = 2πr(h+r)
Surface area of this cylinder = 2(22/7)(5)(10+5)
Surface area of this cylinder = 2(22/7)(5)(15)
Surface area of this cylinder = 157.14 Cm²

Answer:
The Anwer is B because since its not starting at 0,0 its a non porptinatal
Step-by-step explanation:
We want to find 
such that the object needs is in equilibrium:
We're told that 
, 
, and 
. We also know the angle between 
and 
is 95º, which means
is perpendicular to both and , so 
.
If we take the dot product of with the sum of all four vectors, we get
We can do the same thing with and :
Finally, if we do this with , we get
