Ram ram .
Curve surface area of cylinder = 2πrh
Total surface area of cylinder = 2πr(r+h)
Volume of cylinder = πr^2h
now, by formula.
CSA = 2*22/7*7*10
= 440 cm^2
TSA = 2*22/7*7(7+10)
= 44*17
= 748 cm^2
Volume = 22/7*7*7*10
= 1540.

Step-by-step explanation:
In cylinder,
r=7 cm
h=10 cm
Curved surface area of a cylinder
=2×pie×r×h
=2×22/7×7×10
=2×22×10
=44×10
=440 cm^2
Total surface area of a cylinder
=2×pie×r(h+r)
=2×22/7×7(10+7)
=2×22×17
=44×17
=748 cm^2
Volume of a cylinder
=pie×r^2×h
=22/7×7×7×10
=22×7×10
=154×10 =1540 cm^3
