Rectangular sheet is folded with respect to its length to form a cylinder whose CSA is 154 cm^2. If the breadth of the rectangular sheet is 14 cm, find the diameter of the cylinder and the TSA. I leave brainly. I don’t know why but gone! Id pic mei sab hai!

Step-by-step explanation:
given:-
rectangle
Breadth = 14 cm
Length=?
Height = 14 cm
CSA = 154 cm^2
TBA - ?
CSA of a cylinder = 2πrh
154 = 2x 22/7x 14x r
154/88 = r
1.75 cm = r
2x 25 x
145X 1545
=>TEA=
198.25 cm
Diameter 2r = d = 3.5cm
TSA of cylinder = 2πr ( r + h )
TSA = 2 x 22/7 x 1.95 = 15.75
TSA = 11 x 15.75 = 173.25 cm^2
Tell why?? bolo and Id pic me Kuch nahi dik raha hai.
