Answer :-
- Curved surface area of cylinder = 440 cm².
- Total surface area of cylinder = 748 cm².
- Volume of cylinder = 1540 cm³.
Explanation :-
Height of cylinder = h = 10 cm
Radius of cylinder = r = 7 cm
_______________________[Given]
To find : 1) Curved surface area
2) Total surface area
3) Volume of cylinder
Solution :-
1)Curved surface area of cylinder
= 2πrh
= 2 × (22/7) × 7 × 10
= 44 × 10
= 440 cm²
2)Total surface area of cylinder
= 2πr(h + r)
= 2 × (22/7) × 7(10 + 7)
= 44 × 17
= 748 cm²
3)Volume of cylinder
= πr²h
= (22/7) × (7)² × 10
= 22 × 7 × 10
= 1540 cm³
