The area of the circle is given as:

Plugging the value of the radius we have that:

Therefore the area in terms of pi is:
8. 8 is greater than 3 and is all the way to theeft. if it was to the right, you'd need more info
Since
(density = mass/volume), we can get the mass/weight of the liquid by integrating the density
over the interior of the tank. This is done with the integral

which is more readily computed in cylindrical coordinates as

Answer: $2.18
Step-by-step explanation:
You are trying to solve for the cost of one bag or unit cost. Take
