Question

find the circumference of each circle. Take r =22/7 in question 1,r =3.14 in question 2 and r =3.142 in question 3 (i) diameter =49cm​

Answer 1

Answer:

Here given that diameter is 49

Thus radius = 49/2

Circumference of 1st circle using value of pi 22/7

So circumference = 2× 22/7×49/2

= 154

Circumference of 2nd circle using 3.14 =. 2× 3.14×49/2

= 153.86

Circumference of 2nd circle is 153.86

Circumference of 3rd circle using 3.142

2×3.142×49/2

= 153.958

The circumference of 3rd circle is 153.958

So we observe three different circumference of circle using r= 22/7 ,3.14 and3.142

And the circumference are 154 ,153.86 and 153.958

Hope this will help u ☺️
