Question

quantity of milk in litres that can be stored in the tank.
Volume and Surface Area of Solids
Find the volume, curved surface area and total surface area of each of the cylinders whose
dimensions are:
(i) radius of the base = 7 cm and height = 50 cm
(b) radius of the base = 5.6 m and height = 1.25 m
(ili) radius of the base = 14 dm and height = 15 m
A milk tank is in the form of a cylinder whose radius is 1.5 m and height is 10.5 m. Find the
m

Answer 1

Answer:

we know that volume of the cylinder = πr2h Here r = 5.6m h = 1.25 m V = 22/7 × 5.6 × 5.6 × 1.25 V = 123.2 m3 Also we know that curved surface....
