Step-by-step explanation:
The volume of the cylinder is given as πr2h where r= radius of the base of the cylinder and h is
the height of the cylinder.
The volume of the cylinder is given to us as 308 sq meter
∴722×r2×8=308
⇒r2=22×8308×7=12.25
∴r=3.50 m
The lateral surface area of a cylinder is given by the formula =2πrh
=2×722×3.5×8
=176m2
The total surface area of the cylinder = Lateral Surface Area + 2πr2
=176+2722×(3.5)2
=176+77
=253m2
