1)  

A piece of wire was bent to form the following figure. In the figure, there are 4 circles and a line AB. 13 cm of the wire was left over. Find the original length of the wire. (Take π = 227).

                        56





Answer: 4



SOLUTION 1 :

Step1: Total circumference of 4 circles = πD

                                                              = 22 7 x 56

                                                              = 176

where D = total diameter of 4 circles

Step 2: Original length of the wire: 176 + 13 = 189



2)  

A piece of wire was bent to form the following figure. In the figure, there are 4 circles and a line AB. 27 cm of the wire was left over. Find the original length of the wire. (Take π = 227).

                        14





Answer: 2



SOLUTION 1 :

Step1: Total circumference of 4 circles = πD

                                                              = 22 7 x 14

                                                              = 44

where D = total diameter of 4 circles

Step 2: Original length of the wire: 44 + 27 = 71



3)  

A piece of wire was bent to form the following figure. In the figure, there are 4 circles and a line AB. 48 cm of the wire was left over. Find the original length of the wire. (Take π = 227).

                        70





Answer: 4



SOLUTION 1 :

Step1: Total circumference of 4 circles = πD

                                                              = 22 7 x 70

                                                              = 220

where D = total diameter of 4 circles

Step 2: Original length of the wire: 220 + 48 = 268



4)  

A piece of wire was bent to form the following figure. In the figure, there are 4 circles and a line AB. 17 cm of the wire was left over. Find the original length of the wire. (Take π = 227).

                        49





Answer: 4



SOLUTION 1 :

Step1: Total circumference of 4 circles = πD

                                                              = 22 7 x 49

                                                              = 154

where D = total diameter of 4 circles

Step 2: Original length of the wire: 154 + 17 = 171

                        14





Answer: 1



SOLUTION 1 :

Step1: Total circumference of 4 circles = πD

                                                              = 22 7 x 14

                                                              = 44

where D = total diameter of 4 circles

Step 2: Original length of the wire: 44 + 11 = 55
