Answer:
<u>The correct answer is A. You multiplied that tank's radius by two instead of calculating r²</u>
Step-by-step explanation:
This is the wrong calculation we did:
Volume of the cylindrical oil refinery storage tank = π * 2r * h * 0.75
Replacing with the real values, we got:
Volume of the cylindrical oil refinery storage tank = 3.14 * 2 * 95 *80 * 0.75
Volume of the cylindrical oil refinery storage tank = 35,796 cubic feet (Rounded 35,800)
This is the correct calculation we should have done:
Volume of the cylindrical oil refinery storage tank = π * r² * h * 0.75
Replacing with the real values, we got:
Volume of the cylindrical oil refinery storage tank = 3.14 * 95² *80 * 0.75
Volume of the cylindrical oil refinery storage tank = 1'700.310 cubic feet
