what is learn from (pi)

I thing learning some new in life for (pi) through the activity, I will talk about these in flowing points

Background about (pi)

The number π is the ratio of the circumference of a circle to the diameter.
The value of π is approximately 3.14
The diameter of a circle is twice the radius.
Given the diameter or radius of a circle, we can find the circumference.
We can also find the diameter (and radius) of a circle given the circumference.
The formulas for diameter and circumference of a circle are listed below.
We round π to 3.14 in order to simplify our calculations.

D=2*r
C= π*d


How to Measure the diameter of the circle

The distance around a circle is called the circumference. The distance across a circle through the center is called the diameter. π Is the ratio of the circumference of a circle to the diameter? Thus, for any circle, if you divide the circumference by the diameter, you get a value close to . This relationship is expressed in the following formula:

c/d= π

How to calculate the value of (pi)?

This is simple application for (pi)
Example 1:

The radius of a circle is 2 inches. What is the diameter?
Solution:

d=2 * r
d = 2 · (2 in)
d= 4 in

Example 2:

The diameter of a circle is 3 centimeters. What is the circumference?
Solution:
C=pi * d
C= 3.14 · (3 cm)
C= 9.42 cm

Introduction Task Process Evaluation Conclusion References

Introduction back

The electrical transformers are the one of electrical mechanical it appears as statistic machine.
Its function to transfer electrical power and There are many types of transformers its use in various applications like step-up, step-down voltages and currents.

The Task back

Explain why do need to use transformers.
Mention operation components of the transformers.
List six types of transformers.
Calculate the efficiency of the transformers


The Process back

Your task must be done in the form of groups consist of four, each group must have a leaders to distribute the roles, any student has a job, you need to have a journal documenting to write your information, you need to discuss after you information have been gathered.
The groups well divided as flowing:
(Group 1)
Explain why do need to use transformers

Evaluation back

Your evaluation in the form of quiz you can click here to do that. After that in groub you must designed studied about your topic by used mobile device,after the end send me in my E-mail badreldeen2009@yahoo.com

Conclusion back

After the completion of this activity or lesson I'm sure you learned New something's in electrical transformer
Please tell me in my E-Maile badreldeen2009@yahoo.com what did you learn.
