Question

Find the surface area of the cylinders.r=49m,h=20m​

Answer 1

Answer:

Step-by-step explanation:

Surface area of a cylinder

=2πr(r+h)

=2*22/7*49(49+20)

=2*22*7*69

=21252m^2

Answer 2

Answer:

• Total surface area of cylinder = 21232.68 m² (Approx)

Step-by-step explanation:

Given:

• Radius of cylinder = 49 m
• Height of cylinder = 20 m

To Find:

• Total Surface area of cylinder

Now, we know that,

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

⇒ Total surface area of cylinder = 2 × 3.14 × 49(49 + 20)

⇒ Total surface area of cylinder = 6.28 × 49 × 69

⇒ Total surface area of cylinder = 21232.68 m² (Approx)

Hence, Total surface area of cylinder = 21232.68 m² (Approx)

Extra Info:

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

⇒ Curved Surface area of cylinder = 2πrh

⇒ Volume of cylinder = πr²h
