Answer:

Diameter=7m

Height=4m

so, Radius=7÷2=3.5m

ATQ:

sheet of metal required=Total surface area

=2πr(r+h)

=2×22/7×3.5(3.5+4)

=44×0.5×7.5

=44×3.75

=165.00

=165 m^2

Answer:

Sheet of metal required = 165m^2

Step-by-step explanation:

d = 7m

r = 7/2m (or) 3.5m

h = 4m

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

= 2 * 22/7 * 7/2(3.5 + 4)

= 22 * 7.5

= 165m^2
