Question

The curcumfarense of base of a cylander is 180cm and it's height is 30 cm find it's latral surface area​

Answer 1

Answer:

5400 cm²

Step-by-step explanation:

Circumference of base = 180 cm

Circumference = 2πr

Height = 30cm

Lateral surface area of cylinder = 2πrh

= 180 cm × 30 cm

= 5400cm²

Answer 2

Given :-

• The circumfarense of base of a cylinder is 180cm and its height is 30 cm.

To find :-

• Lateral surface area of cylinder

Solution :-

• Circumference of base = 180cm

• Height of a cylinder = 30cm

As we know that

→ Circumference of circle = 2πr

Where " r " is radius

• According to the question

→ Circumference of base = 180cm

Now,

→ Lateral surface area of cylinder = 2πrh

Where " r " is radius and " h " is height

So,

★ Lateral surface area of cylinder

→ 2πrh

→ circumference of base × height

→ 2πr × h

• Put the value of circumference

→ 180 × 30

→ 5400cm²

Hence,

• Lateral surface area of cylinder is 5400cm²
