Hello Rudra
TSA hota hai Total Surface Area
Agar Cylinder ki baat karun, toh curved surface area + top circle + bottom circle hoga total surface area.
Ab iss question mein, humein diya hai ki upar aur neeche se scoop kiya hai humney...
Iska matlab top circle or bottom circle remove kar diya.
Toh, curved surface area lenge hum cylinder ka.
