The volume of the cylinder is $\pi r^2 h$ . The volume of a sphere is $\frac 4 3 \pi r^3$ . In our problem r is the same for both the cylinder and the sphere.

$\pi r^2 h - \frac 4 3 \pi r^3 = \pi(2^2(3) - \frac 4 3 2^3) = \pi(12 - 32/3) = \frac 4 3 \pi \approx 4.19 \textrm{ cubic inches}$

Answer: 4.19 cubic inches

Find a vector function, r(t), that represents the curve of intersection of the two surfaces. the paraboloid z = 9x2 y2 and the p

dolphi86 [110]

The vector function is, r(t) = $\bold{ < t,2t^2,9t^2+4t^4 > }$

Given two surfaces for which the vector function corresponding to the intersection of the two need to be found.

First surface is the paraboloid, $z=9x^2+y^2$

Second equation is of the parabolic cylinder, $y=2x^2$

Now to find the intersection of these surfaces, we change these equations into its parametrical representations.

Let x = t

Then, from the equation of parabolic cylinder, $y=2t^2$ .

Now substituting x and y into the equation of the paraboloid, we get,

$z=9t^2+(2t^2)^2 = 9t^2+4t^4$

Now the vector function, r(t) = <x, y, z>

So r(t) = $\bold{ < t,2t^2,9t^2+4t^4 > }$
