What is the formula for circumference of a circle given the diameter? O C= πr
О С = 2πr
O C = πd
O C= 2πd

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?

Ithink it’s b because it say 3 plastic rings and all the balls
