hii!!
here's ur answer...
1.given:-
radius=5.5cm
height=10cm
TSA=2πr(h+r)
=2×22/7×5.5(10+5.5)
=44/7×5.5×15.5
=852.5/7cm²
2. given:-
radius=10.5cm
height=11.5cm
TSA=2πr(h+r)
=2×22/7×10.5(11.5+10.5)
=44/7×10.5×22
=10164/7
=1452cm²
hope this helps...

(1) Given radius = 5.5cm.
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!
