Circumference of circle is 462 cm.



3)  

Find the circumference of a circle whose diameter is 105cm

Answer: 330cm


SOLUTION 1 :

Given,

d = 105  

circumference of the circle = πd

                                          = 227 x 105

                                          = 22 / 7 x 10515

                                         = 330

Circumference of circle is 330 cm.



4)  

Find the circumference of a circle whose diameter is 77cm

Answer: 242cm


SOLUTION 1 :

Given,

d = 77  

circumference of the circle = πd

                                          = 227 x 77

                                          = 22 / 7 x 7711

                                         = 242

Circumference of circle is 242 cm.



5)
