1a) use integration in spherical coordinates in order to obtain the general formula for the volume of the ball of radius r.
1b) consider the following two solids: the ball of radius 3 centered at the origin and : the cone defined by the condition φ ≤ π/4 where φ is the spherical coordinate with the same symbol. their intersection looks like an ice-cream cone. use integration with spherical coordinates in order to compute the volume of this intersection.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

the answer is 8/21

hope this

$113.42

i hope that is right.
