Given:
The equation of a curve is
To find:
The values of .
Solution:
Formulae used:
We have,
Differentiate with respect to x.
Therefore, the value of is .
Start with the volume equation for a sphere:
V=4/3pi•r^3
The dimensions of the cylinder allow for a sphere with a diameter of 20 centimeters, so the radius of this sphere will be 10 centimeters. Substituting this into the equation:
V=4/3pi•(10)^3
or the uppermost right answer (B).
I think the answer is 4:16 or 1:4. Sorry if it's wrong.
When I set up my problem I got this. $48.50. I'm pretty sure that's right. if not I'm sry
or it is $1.50
