Question

the lateral total surface area and volume of a cylinder whose radius and height are 14m and 20 m is?​

Answer 1

Answer:

• The lateral surface area of a cylinder = 1760 cm²
• Volume of a cylinder = 880 cm³

Step-by-step explanation:

Given that:

• Radius of a cylinder = 14 m
• Height of a cylinder = 20 m

To find:

• The lateral surface area of a cylinder.
• Volume of a cylinder.

Formula used:

• Lateral surface area = 2πrh
• Volume = πr²h

Solution:

Lateral surface area of a cylinder = 2πrh

• Putting the values.

⟹ Lateral surface area = 2 × 22/7 × 14 × 20

⟹ Lateral surface area = 2 × 22 × 2 × 20

⟹ Lateral surface area = 44 × 2 × 20

⟹ Lateral surface area = 88 × 20

⟹ Lateral surface area = 1760

∴ The lateral total surface area of a cylinder = 1760 cm²

Now,

Volume of a cylinder = πr²h

• Putting the values.

⟹ Volume = 22/7 × 14 × 20

⟹ Volume = 22 × 2 × 20

⟹ Volume = 44 × 20

⟹ Volume = 880

∴ Volume of a cylinder = 880 cm³

Answer 2

Given :-

Radius = 14 cm

Height = 20 m

To Find :-

Volume

LSA

Solution :-

We know that

Volume = πr²h

Volume = 22/7 × 14 × 14 × 20

Volume = 22 × 2 × 14 × 20

Volume = 18480 cm

Now

LSA = 2 × 22/7 × 14 × 20

LSA = 44/7 × 14 × 20

LSA = 44 × 2 × 20

LSA = 88 × 20

LSA = 1660 m^3
