VI. Answer the following:
38. A milk tank is in the shape of cylinder with hemisphere of same
radii attached to both ends of it as shown in figure. If the total
height of the tank is 6m and the radius is 1m. Calculate the
maximum quantity of milk filled in the tank in litres. And also
calculate the total surface area of the tank.

Step-by-step explanation:
1000 m^3 = 1 liltre
so, 44 m^3 = 44/1000
= 0.044 lilter
total surface area = 2πrh + 2*2πr^2 sq. unit
= 2πr (h + 2r)
= 2*22/7*1 (6 + 2*1) m^2
= 44/7 (8) m^2
= 352/7 m^2

Answer:
Milk Volume = 23.02Cubic Meter is approximately 23000litres
Surface area= 50.24Square meters
Step-by-step explanation:
Total volume= volume of cylinder+ (volume of 2hemispheres or 1sphere)
= πr^2h+(4/3πr^3)
={3.14×(1×1)×6} + {(4/3)×3.14×(1×1×1)}
=18.84+4.18
=23.02Cubic meter of milk
Total surface area with dish ends= surface area of cylinder+ surface area of two hemispheres / one sphere
= 2πrh+4πr²
={2×3.14×1×6}+{4×3.14×1×1}
=37.68+12.56
=50.24Square meters
