Volume of Cylinder = πr×rh
150π = πrrh
150 = r×r×6
√25 =r
5 = r
total surface area of cylinder = 2πr(h+r)
= 2×3.14×5(6+5) = 110×3.14
= 345.4 cm sq.
curved surface area of cylinder =2πrh
= 2×π×5×6 = 60×3.14
= 188.4 cm sq.
150π = πrrh
150 = r×r×6
√25 =r
5 = r
total surface area of cylinder = 2πr(h+r)
= 2×3.14×5(6+5) = 110×3.14
= 345.4 cm sq.
curved surface area of cylinder =2πrh
= 2×π×5×6 = 60×3.14
= 188.4 cm sq.

345.4cm² and 188.4cm²
Step-by-step explanation:
volume of cylinder = πr²h
150π = πr²h
150 = r×r×6
√25 = r²
5 =r
total surface area = 2πr(r+h)
=2×3.14×5(5+6)
= 110×3.14
= 345.4cm²
curved surface area = 2πrh
=2×3.14×5×6
=60×3.14
= 188.4cm²
