Answer:
Step-by-step explanation:
volume of cylinder=V=πr^2h
given diameter=7 feet
radius=7/2 ft
height=16ft
v=π×7/2×7/2×16
=12.25×16×π
=196π
hope this helps
plzz mark me brainliest
It wouldn't play or else i would help
Answer with Step-by-step explanation:
We are given that

Let g(x,y)=
We have to find the extreme values of the given function


Using Lagrange multipliers



Possible value x=0 or 
If x=0 then substitute the value in g(x,y)
Then, we get 


If
and substitute in the equation
Then , we get possible value of y=0
When y=0 substitute in g(x,y) then we get

Hence, function has possible extreme values at points (0,1),(0,-1), (1,0) and (-1,0).




Therefore, the maximum value of f on the circle
is
and minimum value of 
Answer:
If two things have the same shape and size then they are <em>congruent</em> to one another. If they are only the same shape but not size, then they are similar.
