Answer 1

✌☺Hey dude,☺✌

Diameter of the container=28cm

its radius (r)=14cm

its height (h)=28cm

Area of the sheet required to make the container

$= curved \: surfce \: area \: of \: the \: container \\ + area \: of \: the \: base \: of \: the \: container \\ = 2\pi \: rh \\ = \pi \: r(2h + r) \\ = \frac{22}{7} \times 14(2 \times 20 + 14) \\ = 44 \times 54 = 2376cm {}^{2}$

let the height of cylindrical lid be H1

: . H1 =2cm

$2cm = 2\pi \: rh + \pi \: r {}^{2} \\ = 2 \times \frac{22}{7} \times 14 \times 14 \\ = 176 + 616 \\ = 792cm {}^{2}$

ans:- Area of the sheet required to make the container is 2376sq cm and approximate area of sheet required to make a lid is required to make a lid is 792 sq cm
