A cylidrical oil storage tank has a height of 18 meters and a diameter of 14 meters. If the tank is 50% full, how many kilometers of oil, to the nearest tenth, does it contain?

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

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
