1. The shape of cross-section is a circle.
2. The face parallel to ABCD is EFGH. Since this is a a rectangular shape,
A = L*H = 12*6 = 72 cm^2
3. The cross-section parallel to ABC is DEF with h = 12 ft, b= 5ft (where h is the height and b is the base of a right angled triangle).
Area, A = 1/2 *b*h = 1/2*5*12 =30 ft^2
4. Plane BDHF is a rectangle shape whose length is the diagonal of ABCD.
Diagonal BD = sqrt (AB^2+BD^2) = sqrt (8^2+7^2) = 10.63 cm.
Perimeter, P = 2(BD+DH) = 2(10.63+6) = 33.26 cm
        
                    
             
        
        
        
Answer:
135°
Step-by-step explanation:
To convert from radian measure to degree measure
degree measure = radian measure ×  , so
, so
degree =  ×
 × 
Cancel π on numerator/denominator and 4, 180 by 4, leaving
degree = 3 × 45 = 135°
 
        
                    
             
        
        
        
Answer:
As far as i know you should go for LCM that would be more convenient and easy to do

Answer:
Point estimate for the population variance = 3.92 *  .
 .
Step-by-step explanation:
We are given that a sample of 5 strings of thread is randomly selected and the following thicknesses are measured in millimeters ;
        X                       X -  
                                           
 
       1.13            1.13 - 1.188 = -0.058                                 3.364 * 
       1.15            1.15 - 1.188 = -0.038                                 1.444 *  
    
       1.15            1.15 - 1.188 = -0.038                                 1.444 * 
       1.24           1.24 - 1.188 = 0.052                                 2.704 * 
       1.27           1.27 - 1.188 = 0.082                               <u>  6.724 * </u> <u>    </u>
<u>    </u>
                                                                      <u>= 0.01568   </u>
 <u>= 0.01568   </u>
Firstly, Mean of above data,  =
 =  =
 =  = 1.188
 = 1.188
Point estimate of Population Variance = Sample variance
                                                                =  =
 =  = 3.92 *
 = 3.92 *  .
 .
Therefore, point estimate for the population variance = 3.92 *  .
 .
