Answer:
Volume of a cone 
Step-by-step explanation:
Given that the radius of a cone is 15cm and its height is 4cm
That is r=15cm and h=4cm
To find the volume of a cone :
volume of a cone
cubic units
Now substitute the values in the formula we get
volume of a cone
Now round to nearest hundredth
Therefore Volume of a cone
The question is asking which formula will give the results
1, 9, 36, 100, 225, ...
for k values of
1, 2, 3, 4, 5, ...
You can try them out to see.
A) for k=2, gives 2*3/2 = 3 . . . not 9
B) for k=1, gives 2^3/3 = 8/3 . . . not 1
C) for k=2, gives (2^2*3^2)/4 = 9 . . . . looks promising
D) for k=1, gives 1*2^3/5 = 8/5 . . . not 1
Selection C is the only viable choice. (And the correct one.)
just add the 2 numbers together,
the less expensive player cost $238 and it is $98 less than the more expensive one
more expensive one cost 238 + 98 = $336
Then the number must be between 18² = 324 and 19² = 361. But is that what you want to know?
And irrational number is a number than cannot be written as a simple fraction.
Two good examples of irrational numbers are PI and the square root of 2. These numbers have never-ending decimals, and their decimals never repeat.
