The diameter of a cylindrical water tank is 12ft , and its height is 14ft . What is the volume of the tank?

1 answer:

7 0

So the formula for finding the area of a cylinder is $2 \pi r^{2}+2 \pi rh$ . r=radius. If we put the numbers into the equation it is $2 \pi 6^{2}+2 \pi 6(14)$ We get 6 as the radius because half of 12 is 6. 6 squared is 36 and 6*14= 84. So our equation is now $2 \pi36+2 \pi84$ . 2*pi=6.28318530718 but let's round that to 6.283. So now our equation is much simpler 6.283(36)+6.283(84). Just multiply them. 226.188+527.772= 753.96 is your final answer.

Answer:

I) If method I is used, population of generalization will include all those people who may have varying exercising habits or routines. They may or may not have a regular excersing habit. In his case sample is taken from a more diverse population

II) Population of generalization will include people who will have similar excersing routines and habits if method II is used since sample is choosen from a specific population

Step-by-step explanation:

past excercising habits may affect the change in intensity to a targeted excersise in different manner. So in method I a greater diversity is included and result of excersing with or without a trainer will account for greater number of variables than method II.
