LSA of cylinder = 94.2 cm² and height is given 5 cm
2πrh = 92.4
2 × 22 / 7 × r × 5 = 92.4
r = 92.4 × 7 / 2 × 22 × 5
r = 35574 cm
Volume of cylinder = πr²h
22 / 7 × 35574 × 35574 × 5
= 19886577480 cm³
2πrh = 92.4
2 × 22 / 7 × r × 5 = 92.4
r = 92.4 × 7 / 2 × 22 × 5
r = 35574 cm
Volume of cylinder = πr²h
22 / 7 × 35574 × 35574 × 5
= 19886577480 cm³

hey !!!
Lateral surface area id cylinder = 2πrh
if π = 3.14 h = 5cm
lsa =94.2cm²
so, 2×3.14 × r× 5 = 94.2cm²
=> r = 94.2/31.4
=> r = 3cm..
now volume of cylinder = πr²h
=> 22/7×3 ×3 ×5
=> 3.14×45
=>141.3 cm³ Answer ..
hope it helps!!!
