Let D be the region bounded by the paraboloids z = 8 -
x2 - y2 and z = x2 +
y2. Write six different triple iterated integrals for
the volume of D. Evaluate one of the integrals.
The finite region bounded by the planes z = x, x + z = 8, z =
y,
y = 8, and z = 0 sketch the region in R3 write the 6
order of integration. No need to evaluate. clear writing please
Let H be the hemisphere x2 + y2 + z2 = 66, z ≥ 0, and suppose f
is a continuous function with f(4, 5, 5) = 5, f(4, −5, 5) = 11,
f(−4, 5, 5) = 12, and f(−4, −5, 5) = 15. By dividing H into four
patches, estimate the value below. (Round your answer to the
nearest whole number.) H f(x, y, z) dS

Consider the unit sphere x2 +y2 +z2 = 1 and the cone (z+√2)2 =
x2 +y2. Show that these surfaces are tangent where they intersect,
that is, for a point on the intersection, these surfaces have the
same tangent plane

origin.
