# What is the formula or the circumference with the radius r ?

Relevance
• Oligonucleotides (or oligos) are small nucleic acid polymers, usually less than 20 bases in length. Oligonucleotides can be made by enzymatic cleavage or more commonly via chemical synthesis with polymerases. Oligos have a number of uses from research to disease diagnosis and recently therapeutics.

• It’s C = pi(d). D = 2r

C = 2r(pi)

• To calculate the circumference, simply take the diameter(d) which is twice that of the radius, and multiply it with pi. So the formulae is circumference=(pi)(d)

• The formula is:

C = 2πr

So you just take the radius, multiply it by 2π to get the circumference.

P.S. This is something you could have directly typed into Google rather than waiting for humans to reply. See the link below.
