Answer:
Step-by-step explanation: v=88
πr²h =88
r=2/3
csa=2πrh
2x22/7x2/3x63
264cm²
sa=2πrh+πr²h
264+88
352cm²

Answer:-
- Curved surface area of the cylinder is 264 cm².
- Total surface area is approx 266.79 cm².
Step-by-step explanation:
Given :–
Volume of cylinder = 88cm³
Height of the cylinder = 63 cm
To Find:-
(i) Curved surface area of the cylinder
(ii) Total Surface Area of the cylinder
As we know the formula for the volume of cylinder is πr²h where 'r' is the radius of the cylinder and 'h' is the height of the cylinder.
Therefore according to the question:-
Now we can find values with the help of formula
(i) Curved surface area of cylinder = 2πrh
(ii) T.S.A. of cylinder = 2πr(r + h)
