Asquare piece of paper 10 cm on a side is rolled to form the lateral surface area of a cylinder and then a top and bottom are added.
what is the surface area of the cylinder? (write in terms of pi using symbol)

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

37
