Answer:

154π cm²

Step-by-step explanation:

Height (h) = 4 cm

Surface area of cylinder

= 2πr (h + r)

= 2π (7) (4 + 7)

= 2π (7) (11)

= 2π (77)

= 154π cm²

Answer:

<u>154π cm²</u>

Step-by-step explanation:

<u>Formula for the Surface Area of a Cylinder</u>

<u>Solving</u>

  • Here r = 7 cm and h = 4 cm
  • SA = 2πr (h + r)
  • SA = 2π × 7 (7 + 4)
  • SA = 14π × 11
  • SA = <u>154π cm²</u>
