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
