According to the empirical rule :

68% of the distribution is within 1 standard deviation of the mean ;

That is ; mean ± 1(standard deviation)

68% of subjects :

36 ± 1(4) :

36 - 4 or 36 + 4

Answer:

The  surface area of the square prism is 104\ cm^{2}

Step-by-step explanation:

The surface area of the square prism is equal to  

SA=2b^{2} +4bh

where

b is the length side of the square base

h is the height of the prism

In this problem we have

b=2\ cm

h=12\ cm

substitute

SA=2(2)^{2} +4(2)(12)=104\ cm^{2}

Nesterboy [21]

Answer:

14,130 feet³

Step-by-step explanation:

2r=d

2r=30

r=15

Formula for the volume of a cone is: \frac{1}{3} *b*h

\frac{1}{3} *π*r²*h=

\frac{1}{3} *3.14*15^{2} *60=\\

\frac{1}{3} *3.14*225*60=

\frac{1}{3} *3.14*13,500=\\

\frac{13,500}{3} *3.14=\\

4500*3.14=

14,130 feet³
