Sidney Chen · Answer 1

The surface = pi*10cm2

Step-by-step explanation:

The area of any rectangle is Base * Height,

We know that the square originally has 10cm High, when is rolled to form a cylinder, it's new shape has a bottom side that is equals to a circle.

The length of a circle is 2*pi*Radio = pi*Diameter.

Since the square has the same length in each side, we know that pi*Diameter = 10cm*pi

The surface (area) of the cylinder is = Base * Height = 10cm*10cm*pi
