Question

y Aclosed circular cylinder has diameter 20 cm and height 30 cm. Find the total surface area of the cylinder (x - 3.14)​

Answer 1

Answer:

The Total surface area of the cylinder is 2512 cm²

Answer 2

♡Given:-

⚫ diameter = 20cm.

 Then,

⚫ r = 10cm.

⚫ height = 30cm.

♡To Find:-

⚫ Total surface of the cylinder.

♡Solution:-

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

                                                  ⤏ 2 × 3.14 × 10(10 + 30)

                                                  ⤏ 2 × 3.14 × 10(40)

                                                  ⤏ 2512 cm³

 ∴ Total surface of the cylinder is 2512 cm³.
