An open
cylindrical vessel is made of copper.
The internal diameter of the vessel is 7cm
and its internal depth is 10cm. The metal has
a thickness of 5mm throughout. Find the
capacity of the vessel and volume of copper
used in making it.
Answers
Answer:
Internal diameter = 11.2cm
Internal radius = 11.2/2=5.6cm
Length of the cube = 21cm
Volume of internal cylinder =πr

External radius = R=(5.6+0.4)
Volume of external cylinder = πR

Answer:
1327.32 cm³
1.32732 liter
Step-by-step explanation:
diameter = 7 cm
radies = 6.5 cm
height = 10 cm
metal thick ness = 5mm
volume =Bh or πr²h .
22/ 7 × (6.5)² × 10
1327.32 cm³
1.32732 liter
Metal sheet needed to make the cylindrical vessel=T.S.A of the cylindrical vessel.
2πr(r+h) = 2 × 22/ 7× 6.5 ( 6.5 + 10)
674.14
