Answer 2

Given :

⬤ Radius of Base of Cylinder is 7 cm .

⬤ Height of Cylinder is 20 cm .

To Find :

⬤ Total Surface Area of Cylinder.

Formula Used :

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

• r = radius
• h = height

Solution :

• Radius = 7 cm.
• Height = 20 cm.

According to the Formula :-

2πr (r + h)

2 × 22/7 × 7 (7 + 20)

44 (7 + 20)

308 + 880

1188

Therefore , The Total Surface Area of Cylinder is 1188 cm² .
