Respuesta :

The amount of wallpaper Rocio need to cover the curved surface of the cylindrical podium is 1m².

Curve surface area of a cylinder

  • curve surface = 2πrh

where

r = radius

h = height

Therefore,

r = 0.26 / 2 = 0.13 meters

h = 1.2 meters

Then,

curve surface area = 2 × 3.14 × 0.13 × 1.2

curve surface area = 6.28 × 0.13 × 1.2

curve surface area = 0.8164 × 1.2

curve surface area = 0.97968

curve surface area ≈ 1 m²
