The formula for the area of a circle is A=\pi r x^{2}

The radius if half your diameter,
 
In this case your diameter is 12 so your radius is 6

Then you plug it in the equation, so it is A= \pi  6^{2} or A=36 \pi

This leaves you with the area at about 113.04 centimeters ^{2}

Area is calculated using the value of pi times the square of the
radius. Therefore, the area of a standard compact disc is 113.0976
square centimeters.

what value of b will cause the system to have an infinite number of solutions? y = 6x – b –3x y = –3 b = a:2 b:4 c:6 d:8
bixtya [17]
In order to have an infinite number of solutions, it should be that the two equations are identical. Therefore, I believe the correct answer is option c. The value of b should be 6. Hope this answers the question.

1. Given z_1=5(cos⁡〖20°〗+i sin⁡〖20°〗 ),z_2=4(cos⁡〖10°〗+i sin⁡〖10°〗) find: (Leave answer in polar form.)
coldgirl [10]
By DeMoivre's theorem, you have

z_1=5(\cos20^\circ+i\sin20^\circ)
\implies {z_1}^5=5^5(\cos100^\circ+i\sin100^\circ)

Mrs. Jones Algebra 2 class scored very well on yesterday's quiz. With one exception, everyone received an A. Within how many sta
dem82 [27]
Answer: option B. 2

Explanation:

1) Find the mean:

mean = sum of the values / number of data

The number of data is 12, so:

mean = (91 + 92 + 94 + 88 + 96 + 99 + 91 + 93 + 94 + 97 + 95 + 97) / 12

mean = 1127 /12 = 93.917

2)  Find the variance:

variance = sum of squares of the differences between each data and the media, divided by thenumber of data - 1

variance = (106.97)/(12-1) = 106.97 / 11 = 9.720

3) Find the standard deviation

standard deviation = square root of variance = √(9.720) = 3.118

4) Find the difference of the maximum and the minimun grades with the media:

maximum grade: 99 - 93.917 = 5.083

Find how many standard deviations that is: 5.083 / 3.118 = 1.63

minimum grade: |88 - 93.917| = 5.917

Find how many standard deviations that is: 5.917 / 3.118 = 1.9

5) Conclusion: all the quiz grades falls inside 2 standard deviations form the mean.
