Question

Find the circumference of the circle pictured. Use C = 3.14(2)(r).

Answer 1

The circumference of a circle is
C = 2(pi)r
In this case, r = 2x + 1, so
C = 2(3.14)(2x + 1) = (6.28)(2x + 1) = 12.56x + 6.28

Answer 2

the answer possibilies are A = 12.56n2 - 37.68n + 28.26
A = 12.56n2 + 28.26
A = 6.28n2 - 9.24

Answer 3

How can all your answer choices have n in them when your picture has 2x + 1. Did you copy the wrong picture or the wrong answer choices?

Answer 4

no i didnt they are right

Answer 5

Besides, your answer choices have A for area. Your problem asks for circumference.

Answer 6

my bad im sorry here they are 6.28x + 3.14
3.14x + 6.28
12.56x + 6.28

Answer 7

Didn't I come up with one of those?
