Answer:
f(r) = r/4
Step-by-step explanation:
The volume formula for a cylinder is ...
V = πr^2·h
The total surface area of a cylinder is ...
A = 2πr^2 +2πrh
Then the ratio of volume to surface area is ...
V/A = (πr^2·h)/(2πr(r+h)) = rh/(2(r+h))
__
In this problem, we have h = r, so the ratio becomes ...
V/A = r·r/(2(r+r)) = r/4
As a function of r, this is ...
f(r) = r/4
Answer:
[0, infinity)
Step-by-step explanation:
The square root is a function that is not defined for negative values, since they belong to another space, the complex space.
Having that in mind that means
x>=0
That's it
Answer:
70
Step-by-step explanation:
Dividing is multiplying by the reciprocal.
So 30 divided by 1/2
is like 30(2)=60
Then add 10 so 60+10=
70
