Question

Can you steps please and formula too. ​

Answer 1

Answer:

Area of the sheet = 6.8992 m²

Explanation:

Dimensions of the cylinder :

Height (h) = 1.4m

Radius (r) = 56cm = 0.56m

Required metal sheet =

Total surface area of the cylinder

= 2πr(r+h)

= 2×(22/7)×0.56(0.56+1.4)

= 2×22×0.08×1.96

= 6.8992 m²

Answer 2

Height - 1.4m

radius -56cm- 0.56m

metal sheet required -total surface area

TSA=

$2\pi \: r(r + h)$

According to formula-

2 x 22/7 x 0.56 (0.56+1.4)

2 x 22 x 0.08 (1.96)

44 x0.1568

6.8992m2
