Given height = 10cm.
We know that TSA of the cylinder = 2pir(r + h)
= 2 * 22/7 * 5.5(5.5 + 10)
= 2 * 22/7 * 5.5(15.5)
= 2 * 22/7 * 85.25
= 3751/7
= 535.8cm^2.
(2)Given radius = 10.5cm.
Given Height = 11.5cm.
We know that TSA of the cylinder = 2pirh
= 2 * 22/7 * 10.5(10.5 + 11.5)
= 2 * 22/7 * 10.5(22)
= 2 * 22/7 * 231
= 10164/7
= 1452cm^2.
Hope this helps!
