The water tank

The water tank has the shape of a sphere with a radius of 2 m. How many liters of water will fit in the tank? How many kilograms of paint do we need to paint the tank, if we paint with 1 kg of paint 10 m2?

Correct answer:

V =  33510.3216 l
m =  5.0265 kg

Step-by-step explanation:

r=2 m V1=43 π r3=43 3.1416 2333.5103 m3  V=V1 l=V1 1000  l=33.5103 1000  l=33510.322 l=33510.3216 l=3.351104 l
S=4π r2=4 3.1416 2250.2655 m2 h=10 m2/kg  m=S/h=50.2655/10=5.0265 kg
