Answer 1

Answer:

volume of a bottle = 4312

Answer 2

Answer:

• Volume of bottle is 539 cm³.
• Surface area o bottle is 385 cm².
• Curved surface area of bottle is 308 cm².

Explanation:

Given :-

• Height of bottle is 14 cm.
• Diameter of bottle is 7 cm.

To find :-

• Volume of bottle.
• Surface area of bottle.
• Curved surface area of bottle.

Solution :-

We need Radius of bottle :

Radius = Diameter/2

⇒Radius = 7/2

⇒Radius = 3.5

Radius of bottle is 3.5 cm.

• We know, Shape of bottle is cylinder.

So,

Volume of cylinder = πr²h

Where,

• r is radius of cylinder.
• h is height of cylinder.

Put all values :

⇒22/7 × (3.5)²× 14

⇒22/7 × 12.25 × 14

⇒3773/7

⇒539

Volume of bottle is 539 cm³.

Surface area of cylinder = 2πrh + 2πr²

⇒2 × 22/7 × (3.5) × 14 + 2 × 22/7 × (3.5)²

⇒2 × 22/7 × 49 + 2 × 22/7 × 12.25

⇒2156/7 + 539/7

⇒308 + 77

⇒385

Surface area of bottle is 385 cm².

Curved surface area of cylinder = 2πrh

⇒2 × 22/7 × 3.5 × 14

⇒44/7 × 49

⇒2156/7

⇒308

Curved surface area of bottle is 308 cm².
