(3-4) Area of a Circle.






                          The area of a circle is the space inside of it. The area of a
                          circle equals Pi multiplied by the radius square or,





                                                                          Diameter = 4mm

                            To calculate the approximate area of a circle with
                            a radius of 5 cm:
