Answer:

✔️the total surface area of the cylinder is 1408 cm²

Step-by-step explanation:

Solution:⤵️

Given,

  • 50 circular plates each with diameter 14 cm
  • 50 circular plates each with diameter 14 cmRadius of circular plates = 7cm

✔️Thickness of plates = 0.5 cm

✔️As these plates are one above the other, the total thickness of all the plates = 0.5 x 50 = 25 cm

↪️So, the total surface area of the right circular cylinder formed = 2πr × h + 2πr²

= 2πr (h + r)

= 2(22/7) x 7 x (25 + 7)

= 2 x 22 x 32 = 1408 cm²

Therefore, the total surface area of the cylinder is 1408 cm²
