Answer:

6.1 hrs

Step-by-step explanation:

Volume of the cylinder = pi * (10/2)^2 * 1.4 m^3 = 109.956 m^3

So, time required = 109.953/18 hrs = 6.108 hrs ≈ 6.1 hrs

When you are multiplying exponents with the same base, you can add the exponents. This is represented as:

x^a \cdot x^b = x^{(a +b)}


In our case we are multiplying exponents with the same base 8 and exponents -7 and 5. The sum of -7 and 5 is -2, so our answer is \boxed{8^{-2}}.
