so we would solve this like:
out here we are using the formula to find the circumference , to find the radius becoz radius id double of the diameter so if we find the radius , we can multiply if with 2 to get the diameter so here we go
Circumference=2*pi*r (now we will put 62.8 as circumference , 3.14 as pi and as we dont know radius we will assume it as r)
62.8 = 2 * 3.14 * r
62.8 = 6.28 * r
62.8 = 6.28r
r = 62.8 / 6.28 ( now deviding them both will give us our radius)
r = 10cm
So now we've got our radius as 10cm and so we will multiply it by 2 to get our diameter !
10 * 2 = 20 DIAMETER
Now we have got our answer or diameter which is 20cm!
I hope you've understood by now but if not then pls be free to ask!
i hope this helps!
and if you want to check that the answer is correct or not then you can put radius as 10 in its place and solve to get the circumference using the same formula i told u!
