hey mate !!!❤✌
here's ur answer ⤵⤵⤵
first let's know the circumference and its formula ...
like we have perimeter in square rectangle etc... the same is circumference of circle ....
perimeter of Circle = circumference of Circle ....
now let's know it's formula !!!!!
2πr °°°° π = 3.14 // 22÷7
as we know that diameter is twice of radius... it means 2r = D...... r =D/2 so let's eject it in formula ..
2π(D/2)
2 cancels
formula becomes : πd
⭐ hope it helps ⭐
