Answer 2

Answer:

Step-by-step explanation:

Formula :-

Volume of cylinder = πr²h

Answer 1 :-

Given :

Radius of the base = 14 cm

Height = 36 cm

Solution :-

⇒Volume of cylinder = πr²h

⇒Volume = 22/7 × (14)² × 36

⇒Volume = 22/7 × 14 × 14 × 36

⇒Volume = 22 × 2 × 14 × 36

⇒Volume = 44 × 504

⇒Volume of cylinder = 22176cm³

Answer 2 :-

Given :

Radius of the base = 21 cm

Height = 1.5m = 150cm

Solution :-

⇒Volume of cylinder = πr²h

⇒Volume = 22/7 × (21)² × 150

⇒Volume = 22/7 × 21 × 21 × 150

⇒Volume = 22 × 3 × 21 × 150

⇒Volume = 66 × 3150

⇒Volume of cylinder = 207900cm³

Answer 3 :-

Given :

Diameter of base = 7m

Radius = Diameter/2 = 3.5m

Height = 5m

Solution :-

⇒Volume of cylinder = πr²h

⇒Volume = 22/7 × (3.5)² × 5

⇒Volume = 22/7 × 3.5 × 3.5 × 5

⇒Volume = 22/7 × 12.25 × 5

⇒Volume = 22 × 12.25 × 5 /7

⇒Volume = 1347.5/7

⇒Volume of cylinder = 192.5m³
