Answer:
671.91 m^2.
Step-by-step explanation:
Diameter of cylinder and hemisphere =7m
Radius =7/2
Radius=3.5m
Height of cylinder = Height of oil tanker-Height of two hemispheres
Height of cylinder=20-2(3.5)
=20-7
=13m
Amount of oil =Volume of cylinder+Volume of 2 hemispheres
= π×r^2h+2×2/3×π×r^3
=π×r^2(h+4/3×r)
=22/7×3.5×3.5(13+4/3×3.5)
=11×3.5(13+14/3)
=38.5(17.66)
=679.91 m^2
