To know the mass of the sphere given the density , we first define density as

D = Mass / volume

now we have a value of density but doesn't have volume so we compute for it using the given radius 5.5 cm

V = (4/3)πr^3

so
mass = D (volume)
mass = 11.34 ((4/3)π(5.5)^3 )

mass = 7902.96 g

Hope my answer would be a great help for you.

28/z- z/4+1 1/8 when z =4

Paha777 [63]

Answer:

7 1/8 or 7.125

Step-by-step explanation:

first subsitute z for 4

28/4 - 4/4 + 1 1/8

then do 28/4 - 4/4 which is 6,

add that to 1 1/8

and get 7 1/8

Find all polar coordinates of point p where p = (6, -pi/5)

Lelu [443]

Given a point in coordinates form $(r,\theta)$ , one can compute the cartesian form like this:
$(r\cos\theta,r\sin\theta )$
We have:
$r=6,\theta=-\dfrac{\pi}{5}$
We get the cartesian form then:
$\left(6\cos-\dfrac{\pi}{5},6\sin-\dfrac{\pi}{5}\right)$
