Question

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

Answer 1

TSA of cylinder= 2πr(r+h)

= 2×22/7×4(4+10)

=44/7×4×14

=44×4×2

= 352

please follow me

Answer 2

Given :

⬤ Radius of Cylinder is 4 cm.

⬤ Height of Cylinder is 10 cm .

To Find :

⬤ Total Surface Area of Cylinder.

Formula Used :

$\bf[\:{T.S.A \: of \: Cylinder\: is = 2\pi{r}\:(r+h)}\:]$

• r = radius
• h = height

Solution :

According to the Formula :-

2πr (r + h)

2 × 22/7 × 4 (4 + 10)

44/7 × 4 (4 + 10)

176/7 × 14

176 × 2

352

Therefore , Total Surface Area of Cylinder is 352 cm².
