This is going to be hard to describe without an image but I'll try my best. Imagine there is a parallelogram ABCD. AB is the slant length on one side and CD is the slant length on the other.
So BD is the top and AC is the base.

The base (AC) is 10cm. The slant length is 8cm. The perpendicular height from base to top is 7 cm.

What is the area of the parallelogram?
I think its 84cm squared but would like confirmation.

Now the harder part (at least for me). What is the perpendicular distance from AB to CD?
Does it just remain 12 (the base)?

Hello,

Currently in calc we're learning about cylindrical and spherical coordinates.

One of the questions that I cannot figure out is finding the volume of a cylinder with height H and radius R using SPHERICAL coordinates not cylindrical. Assuming that phi is the angle in the xy-plane and theta the azimuthal angle from the z-axis. So the format would be ∫∫∫ p^2 sinθ dp dθ dφ . So I think the first integral; the limits of phi should be from 0 to 2π but the next two I don't know.

Any help would be appreciated

thanks
