A cylindrical container, closed at both ends, has a radius of 7cm and height 5cm [Take π = 22/7]

Find the total surface area of the container

  • A.
    35cm3
  • B.
    154cm3
  • C.
    220cm2
  • D.
    528cm2
  • E.
    770cm2
Correct Answer: Option D
Explanation

T.S.A of a cylinder = (2pi r^2 + 2pi rh)

= (2pi r(r + h))

= (2 times frac{22}{7} times 7 times (7 + 5))

= (44 times 12)

= (528 cm^2)
