Answer 2

Correct Question :

• The diameter of cylinder is 12cm and height is 14cm . Find the surface area of the cylinder

Answer :

• Surface area of cylinder is 754.2 cm²

Given :

• Diameter of cylinder is 12cm
• Height if cylinder is 14cm

To find :

• Surface area of cylinder

Solution :

Given that,

• Diameter is 12cm ,

Radius = D/2 = 12/2 = 6cm

As we know that,

• Surface area of cylinder = 2πr(r + h)

Where , r is radius 6cm and h is height 14cm

》2πr(r + h)

》2 × 22/7 × 6 (6 + 14)

》37.71 (6 + 14)

》37.71(20)

》754.2 cm²

Hence , Surface area of cylinder is 754.2 cm²

More Explanation :

• Curved surface area of cylinder = 2πrh
• Volume of cylinder = πr²h
