Answer:
I think it might be 30pi m or 94.2 m.
Step-by-step explanation: So you are finding the perimeter of the circle. You have a radius of 15, the perimeter for a circle is C=2pir. Now we can do C=2pi(15). The answer is 30pi or C=2 x 3.14 x 15= 94.2 Hope this helps.
<u>From the problem statement:</u>
n = "a number"
seven less than twice a number is -1
* now i'll underline the changes made by interpreting the way the question was written:
<u>7</u> less than <u>two times</u><u> </u><u>n</u> is -1
7 less than <u>2*</u><u>n</u> <u>equals</u> -1
<u>take away 7 from</u> <u>2n</u> <u>=</u> -1
2n <u>take away 7</u> = -1
2n <u>-</u> 7 = -1
<u><em>2n - 7 = -1</em></u>
<u><em>answer is: (A)</em></u>
