A bead is made from material with constant density 7 grams per cubic millimeter by drilling a cylindrical hole of radius 2 mm through a sphere of radius 7 mm. a. Set up a triple integral in cylindrical coordinates representing the mass of the bead in grams (do not include units).
b. Find the mass of the bead.

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

might be the correct answer will be question number 2

the answer is: -22 also a

hope i

-lavira: )

you meant circumference well the answer is:

17.27876 miles

area is 23.7583

the radius is 2.75 miles

hope this hmu if needed.
