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