Answer:
Step-by-step explanation:
(i) Volume of Cylinder = πr²h = 23562 cm³
(22/7) × r² × 17 = 23562
r = 21 cm
Curved Surface Area (C.S.A) of Cylinder = 2πrh
= 2 × (22/7) × 21 × 17
= 2244 cm²
Total Surface Area (T.S.A) of Cylinder = 2πr(h+r)
= 2 × (22/7) × 21 × (17+21)
= 5016 cm²
(ii) Volume = πr²h = 1078 cm³
(22/7) × r² × 7 = 1078
r = 7 cm
C.S.A = 2πrh
= 2 × (22/7) × 7 × 7
= 308 cm²
T.S.A = 2πr(h+r)
= 2× (22/7) × 7 × (7+7)
= 616 cm²
