Well, this is a stem and leaf problem. 

The numbers are 20, 28, 29, 29, 31, 32, 36, 41, and 42. 

In order to solve for the mean, we find the average and we add the numbers together and divide by 9(there are 9 numbers). 

The mean is 32.
The median is the middle number, or 31.

To find the mean you have to add all of the numbers then divide by the total number of numbers so-20+28+29+29+31+32+36+41+42=288 then divide by 9=32 therefor the answer to number 1 is d
to find the median eliminate the numbers on the outside till you find the middle one
20 28 29 29 31 32 36 41 42
     28 29 29 31 32 36 41
          29 29 31 32 36
               29 31 32
                    31
therefor the median is 31

a cylindrical pipe made of metal 3 m long is 3 cm if the internal radius of the pipe is 10 cm what is the volume of metal used i
cricket20 [7]

Answer:

857.766cm^3

Step-by-step explanation:

Given data

Lenght = 3m

Internal radius r = 3m

External radius R= 10m

Volume of pipe= πr^2h

Volume of metal= External - Internal

Volume= πR^2h-πr^2h

Volume= πh(R^2-r^2)

Volume= 3.142*3(10^2-3^2)

Volume= 3.142*3(100-9)

Volume= 9.426*(91)

Volume= 857.766cm^3

Hence the volume of the metal is 857.766cm^3
