Asquare with an area of 81cm^2 is rotated to form a cylinder. what is the height of the cylinder

9 cm

Step-by-step explanation:

All the lengths of the sides of a square are equal. Therefore the formula for the area of a square is:

Where l is the length of one of its sides.

We know the area of this square.

Now we equate both equations and solve for l.

If the length of the sides of the square is 9 cm, this implies that the height of the square is 9 feet.

Then, the height h of the cylinder that is formed when rotated this square is

139 divided by a number
