Answer:
Step-by-step explanation:
2*π*r=44cm.
r = 44/2π
r = 44*7/22*2
r = 7
Volume = π* (r^2)* 7
V = (22/7)*7*7
V =22*49
Volume = 1078 cm^3
Surface Area = 44*7
Surface Area = 308cm^2

SolutioN :-
- Circumference of the base of cylinder = 44cm.
- Height of the cylinder = 10cm.
As we know that,
★ Circumference of cylinder = 2πr.
⇒ 2πr = 44.
⇒ 2 x 22/7 x r = 44.
⇒ 44/7 x r = 44.
⇒ r = 7cm.
★ Curved surface area of cylinder = 2πrh.
⇒ 2 x 22/7 x 7 x 10.
⇒ 2 x 22 x 10 = 440cm².
