Answer:
7.7 square metres or 7.669 square metres of metal sheet
Step-by-step explanation:
Volume of cylinder = 2×22/7×r×100cm
15.4 litres = 15,400 cm cube
Radius = 15 400×7/22 × 50
= 98cm
Surface area of cylinder = (2×22/7×49^2) + (2×22/7×49 × 100)
= 15 092 + 61 600
= 76 692 square cm
= 7.669 square metres of metal sheet required

Answer:
x = 20
y = 28
Step-by-step explanation:
hari's age: x
harry's age: y
7x = 5y
4(x+4) = 3(y+4)
4x+16 = 3y+12
4x+4 = 3y
5/3(4x+4) = 5y = 7x
20/3x +20/3 = 7x
20/3 = 1/3x
x = 20
y = 28
