answer
given
v=2100cm³
h=3r
v=1/3πr²h
soln
v=1/3πr²h
2100cm³=1/3×π×r²×3r( you will insert 3r in the place of h.)
2100cm³=3π/3×r³(cancel 3 by 3)
2100cm³= πr³
r³=2100cm³/3.14 ( π=3.14)
¾r³=¾2100cm³/3.14(I make them cube root.sorry I can't use the real cube root so I replace it by ¾)
r=8.74…

Answer:
pradis has more orange slices
reason:The ratio of apple slices to the total number of slices on Praxis plate is 4 to 11. This means for every 11 slices in Praxis plate, 4 of them are apple slices and 7 of them are orange slices. This also shows the total number of slices in Praxis plate is a multiple of 11.
First possibility of total number of slices in Praxis plate is 11. Another possibility of total number of slices in Praxis plate is 11 x 2 = 22. Since, it is given that total number of slices are not more than 20, so 22 slices are not possible in Praxis plate. So, the only possibility is 11 slices. From here we can conclude that: Number of slices in Pam Plate:
The ratio of the total number of slices to orange slices on Pam plate is 13 to 6. This means for every 13 slices in Pam's plate there are 6 orange slices and 7 apple slices. This also show the total number of slices in Pam's plate is a multiple of 13.
The first possibility of total number of slices in Pam's plate is 13. The next possibility is 13 x 2 = 26 slices. But since the number of slices cannot be above 20, the only possibility is that there are 13 slices in Pam's plate. From here we can conclude that:
Answer:
B. x= 4
Step-by-step explanation:
We know that,
The result for the intersection of the secant and the tangent is given by by the figure below,
According to the question, we have,
i.e. 
i.e. 
Now, the solution of a quadratic equation 
is given by, 
So, we get,
implies a= 1, b= 12 and c= -64.
Thus, the solution is given by,
i.e. 
i.e. 
i.e. 
i.e. 
and i.e. 
i.e. 
and i.e. 
i.e x= -16 and x= 4.
Since, length cannot be negative.
So, we have, x= 4.
