Given : cylindrical vessel of base radius r cm and height h cm opened at one end
To Find : total surface area
A) (πr² + 2πrh) cm²
(B) 2πrh cm²
(c) πr²h cm²
(D) (πr2 + h) cm²
Solution:
cylindrical vessel of base radius r cm and height h cm opened at one end
CSA - Curved surface area = 2πrh
Base Area = πr²
Top area = 0 at open on one end
Total surface area = 2πrh + πr²
= (πr² + 2πrh) cm²
Total surface area = (πr² + 2πrh) cm²
