Question

If the radius of a cylinder is 4cm and height is 10cm, then the total surface area of a cylinder is:

Answer 1

Given :-

• If radius of cylinder is 4cm

• If height of cylinder is 10cm

Solution :-

Here, Radius of a cylinder is 4cm

Height of the cylinder is 10cm

Now,

As we know that,

Total surface area of cylinder = 2πr(r + h)

Put the required values ,

TSA of a cylinder = 2 * 22/7 * 4 ( 4 + 10 )

TSA of a cylinder = 2 * 22/7 * 4 * 14

TSA of cylinder = 2 * 22 * 4 * 2

TSA of cylinder = 44 * 4 * 2

TSA of cylinder = 44 * 8

TSA of cylinder = 352cm^2

Hence, The total surface area of cylinder is 352cm^2 $.$

Answer 2

Answer:

• The total surface area of a cylinder is 352 cm².

Step-by-step explanation:

Given that:

• The radius of a cylinder is 4 cm.
• Height is 10 cm.

To Find:

• The total surface area of a cylinder.

Formula used:

• Total surface area of a cylinder = 2πr(r + h)

Here,

• Radius of cylinder is denoted as r.
• Height of cylinder is denoted as h.

Finding the total surface area of a cylinder:

• Total surface area of cylinder = 2 × π × 4 cm × (4 cm + 10 cm)
• Total surface area of cylinder = 2 × π × 4 cm × 14 cm
• Total surface area of cylinder = (2 × 22 × 4 cm × 14 cm)/7
• Total surface area of cylinder = 352 cm²
