What is the smallest integer n such that n\sqrt{2} is greater than 20

Consider the integral: 4 0 16 − y2 − 16 − y2 4 1 x2 + y2 dz dx dy . (a) describe w. use the standard view of the x, y, and z axes. front half of a cone with a rounded top. full cone with a flat top. right half of a cone with a flat top. front half of a cone with a flat top. right half of a cone with a rounded top.

Simplify the expression and find the missing terms. the simplest form of has in the numerator and in the denominator.
