(1) The perimeter of the square is times the diameter of the
circle, and the circumference is
than the perimeter
of this square
(2) The perimeter of the regular hexogon is times the radius.
This means it is times the diameter. The perimeter of this
regular hexagon is slightly
than the
circumference
(3) We know from (1) and (2) that the circumference is slightly longer
than times the diameter, and shorter than Times the
diameter

we are given scale of 2 units.

on graph paper the space is 2.5 cm.

length of glass = 8 units.

8 units = 2 units +2 units +2 units +2 units.

each 2 unit is = 2.5cm.

therefore,

8 units = 2 units +2 units +2 units +2 units = 2.5+2.5+2.5+2.5= 10cm.

therefore, the height of the the actual glass in cm is 10 cm.

In  mathematics, the  pythagorean theorem, also known as  pythagoras' theorem, is a fundamental relation in  euclidean geometryamong the three sides of a  right triangle. it states that the square of the  hypotenuse  (the side opposite the  right angle) is equal to the sum of the squares of the  other two sides. the  theorem  can be written as an  equationrelating the lengths of the sides  a,  b  and  c, often called the "pythagorean equation".
