Circumference of circle is 132 cm.



2)  

Find the circumference of a circle whose diameter is 49cm

Answer: 154cm


SOLUTION 1 :

Given,

d = 49  

circumference of the circle = πd

                                          = 227 x 49

                                          = 22 / 7 x 497

                                         = 154

Circumference of circle is 154 cm.



3)  

Find the circumference of a circle whose diameter is 133cm

Answer: 418cm


SOLUTION 1 :

Given,

d = 133  

circumference of the circle = πd

                                          = 227 x 133

                                          = 22 / 7 x 13319

                                         = 418

Circumference of circle is 418 cm.



4)  

Find the circumference of a circle whose diameter is 147cm

Answer: 462cm


SOLUTION 1 :

Given,

d = 147  

circumference of the circle = πd

                                          = 227 x 147

                                          = 22 / 7 x 14721

                                         = 462

Circumference of circle is 462 cm.



5)  

Find the circumference of a circle whose diameter is 119cm

Answer: 374cm


SOLUTION 1 :

Given,

d = 119
