Question

If diameter=14cm, h=13cm, then find the total surface area of cylinder.​

Answer 1

Answer:

Formula of TSA is 2πr sq h

2 ×22/7×7×7×13

4004 cm sq

Answer 2

Given :

⬤ Diameter of Cylinder = 14 cm .

⬤ Height of Cylinder = 13 cm .

To Find :

⬤ Total Surface Area of Cylinder .

Formula Used :

$\sf[\:{Total\:Surface\:Area\:of\:Cylinder=2\pi{r}(r+h)}\:]$

• r = Radius
• h = Height

Solution :

First , We have to Calculate Radius of the Cylinder . Hence ,

• Diameter = 14
• Radius = 14/2 = 7 cm

According to the Formula :

2πr (r + h)

2 × 22/7 × 7 (7 + 13)

44 (7 + 13)

44 (20)

880

Therefore , The Total Surface Area of Cylinder is 880 cm² .
