Answer:
Given :-
- A cylinder has base radius is 14 cm and height is 21 cm .
To Find :-
- Area of the base .
- C.S.A of cylinder .
- T.S.A of cylinder .
- Volume of cylinder .
Formula Used :-
❶ Area of the base :
✮
❷ C.S.A of the cylinder :
✮
❸ T.S.A of the cylinder :
✮
❹ Volume of the cylinder :
✮
Solution :-
Given :
- Radius (r) = 14 cm
- Height (h) = 21 cm
❶ Area of the base :
⇒ Area =
⇒ Area =
⇒ Area =
⇒ Area = 22 × 28
➠ Area = 616 cm²
The area of the base is 616 cm² .
❷ C.S.A of the cylinder :
⇒ C.S.A =
⇒ C.S.A = 2 × 22 × 2 × 21
➠ C.S.A = 1848 cm²
The curved surface area of the cylinder is 1848 cm² .
❸ T.S.A of the cylinder :
⇒ T.S.A =
⇒ T.S.A =
⇒ T.S.A = 2 × 1540
➠ T.S.A = 3080 cm²
Total surface area of the cylinder is 3080 cm² .
❹ Volume of the cylinder :
⇒ Volume =
⇒ Volume =
⇒ Volume =
⇒ Volume =
⇒ Volume = 22 × 588
➠ Volume = 12936 cm²
The volume of the cylinder is 12936 cm² .
