The diameter of a cylindrical water tank is 12ft , and its height is 14ft . What is the volume of the tank?
1 answer:
So the formula for finding the area of a cylinder is 
. r=radius. If we put the numbers into the equation it is 
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*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:
Step-by-step explanation:
Given that initial population is 3100
The population is decreasing continuously which means the population at any time t can be represented by the funciton
where t = time and r = rate
The population is continuously decreasing at the rate of r% per unit of time.
When t becomes very large,
we get limit would be P0 (0) =0
The population will decrease and almost tend to 0 as time advances.
There is no chance for further decrease as population cannot be negative
So limiting population is 0.
