Question

The surface area of a cylinder whose base radius is 14 cm and height is 28 cm is

Answer 1

Volume of the cylinder=

π(7)2×10=227×72×10=1540 cm3

Answer 2

Given :

⬤ Radius of Cylinder is 14 cm .

⬤ Height of Cylinder is 28 cm .

To Find :

⬤ Surface Area of Cylinder.

Formula Used :

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

Solution :

According to the Formula :-

2πr (r + h)

2 × 22/7 × 14 (14 + 28)

2 × 22 × 2 (24 + 28)

44 × 2 (14 + 28)

88 (14 + 28)

88 (42)

3696

Therefore , Surface Area of Cylinder is 3696 cm² .
