Answer: See explanation
Step-by-step explanation:
To solve this, firstly, we need to calculate the volume of the cylinder which will be:
= πr²h
where r = diameter/2 = 14/2 = 7
h = 18
Volume = πr²h
= 3.14 × 7² × 18
= 3.14 × 49 × 18
= 2769.48meters³
Since the tank is 50% full, the amount if oil it contains will be:
= 50% × 2769.48
= 0.5 × 2769.48
= 1384.74m³
= 1.38km³
