11.
A cylindri​

Answer 1

Answer:

848.57

Step-by-step explanation:

since it is rolled along its length then height of cylinder = length of rectangular paper = 22 cm & width = diameter of cylinder

radius = 10/2 = 5cm

total surface area = 2πr(r + h)

= 2×22/7×5(5+22)

= 44/7 * 135 = 848.57 cm^2
