Circumference of circle is 154 cm.



3)  

Find the circumference of a circle whose diameter is 126cm

Answer: 396cm


SOLUTION 1 :

Given,

d = 126  

circumference of the circle = πd

                                          = 227 x 126

                                          = 22 / 7 x 12618

                                         = 396

Circumference of circle is 396 cm.



4)  

Find the circumference of a circle whose diameter is 63cm

Answer: 198cm


SOLUTION 1 :

Given,

d = 63  

circumference of the circle = πd

                                          = 227 x 63

                                          = 22 / 7 x 639

                                         = 198

Circumference of circle is 198 cm.



5)
