V of cylinder = πr²h
h=V /(πr²)
h=27/π -exact value
h=1323/(3.14*(7)²)= 8.6 cm - approximate value
Given:

To find:
The value of
.
Solution:
We know that,


It means, we have
and we need to find the value of
.




Therefore, the value of
is 0.8.
I'm not sure if this is the answer you are looking for, but the number before a variable is called a coefficient.
