Answer 2

Given,

The soaps are in the shape of a cylinder.

To Find,

The surface area of the soap.

Solution,

Given that,

Cylindrical shape, soap bars are company making.

The soap's diameter is 5cm and height is 2cm.

It's a cylindrical shape.

The surface area of cylinder 2$\pi rh + 2 \pi r^{2}$

$2\pi r(h+r)$ =

r = 5/2

2.5cm.

Height h = 2cm.

$\pi$ = 3.14

2* 3.14 * 2.5(2+2.5)

= 70.65 cm².

Hence, the surface area of the soap bar is 70.65cm².
