Question

A Closed Cylindrical rank of radius 7m height 3m is made from a sheet of metal. How mych sheets of metal is required?

Answer 1

Solutions :-

Given :
Radius of cylindrical tank = r = 7 m
Height of cylindrical tank = h = 3 m


Find how much sheets of metal is required :-

Total surface area of cylinder = 2πr(h+r) sq. unit
= 2 × 22/7 × 7 (3 + 7) m²
= 2 × 22 × 10 m²
= 440 m²


Hence,
440 m² of metal sheets are required.

Answer 2

Given: Radius of cylindrical tank  = 7 m

Height of cylindrical tank  = 3 m

Total surface area of cylindrical tank

= 2πr(h+r)

= 2*22/7*7(3+7)

= 44 * 10 = 440 m²

Hence 440 m² metal sheet is required.
