<h2><u>Solution</u> :-</h2>
Given : Radius of cylinder = 8 m
Height = 4 m
Volume of cylinder = πr²h cu. units 
= 22/7 × 8 × 8 × 4 m³
= 804.57 m³ (approx.) 
Curved surface area = 2πrh sq. units 
= 2 × 22/7 × 8 × 4 m²
= 201.14 m² (approx.) 
Total surface area = 2πr(r + h) sq. units
= 2 × 22/7 × 8 (8 + 4) m²
= 2 × 22/7 × 8 × 12 m²
= 603.43 (approx.)
