The area of a circle is represented by the formula pi * radius raised to the power of 2. The circumference of the circle meanwhile is equal to 2 pi * radius. when the both are equal: pi r^2 = 2 pi r. In this case, pi and r cancels our. Hence the radius is equal to 2 units.

i believe your answer is b.

good luck!

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?
