Find The Surface Area Of The Cylinder In Terms Of Pi class=

Sagot :

Answer:

104π cm²

Step-by-step explanation:

Surface Area of cylinder

  • SA = 2πrh + 2πr²
  • SA = 2πr (h + r)
  • r is the radius and h is the height

Given (from the figure)

  • r = 4 cm
  • h = 9 cm

Solving

  • SA = 2πr (h + r)
  • SA = 2π × 4 (9 + 4)
  • SA = 8π × 13
  • SA = 104π cm²
