Answer:
Step-by-step explanation:
Newton's cooling model is:
Where
t is the time in hours
is the ambient temperature
is the initial temperature of the body
We know that:
Then after 7 hours the temperature of the liquid will be:

The diagonal of square is a√2
the half of it a√2/2=12
a=12*2/√2=12√2
S=a^2=12√2*12√2=288
The formula for the volume of a cylinder is V=3.14r^2(h).
So substituting the volume: 20,403.72=3.14r^2(h).
To solve for ‘r’, divide both sides by 3.14h
r^2=6,498/h
Then find square root of both sides
r= sqrt(6,498/h)
Since ‘h’ is not specified here, it cannot be solved further.
