Question

a closed cylinder tank of radius 7 M and height 3M is made from a sheet of metal how much sheet of metal is required

Answer 1

Total surface area of cylinder=2πr(r+h)

=2×22÷7×7(7+3)

=44×1×10

=440 sq.m

440 sq.m of metal sheet will required for cylinder.

Answer 2

Answer:

132 m²

Step-by-step explanation:

total metal required indicates TSA

TSA of cylinder = 2πr(r+h)

LSA = 2×22 ÷7×7(7+3)

       =440m²
