The gas tank has the shape of a sphere with a diameter of 17.8 m. How many cubic meters of gas can it hold? How many kilograms of paint are needed to paint a gas tank if 1 kg of paint is enough to paint about 6 square meters?

Correct answer:

V =  2952.9672 m3
m =  165.897 kg

Step-by-step explanation:

D=17.8 m r=D/2=17.8/2=1089=8.9 m  V=34 π r3=34 3.1416 8.93=2952.9672 m3
h=1/6=610.1667 kg/m2  S=4π r2=4 3.1416 8.92995.3822 m2  m=S h=995.3822 0.1667=165.897 kg
