Answer:
-5
Step-by-step explanation:
First simplify the number part, 14/2 = 7/1
then the x part,

y doesn't need to be simplified
then simplify the z part, z^-6 = z^6
put it all together...
468 seats is the answer.
26 x 18
or
13 x 2 x 9 x 2
both equal 468
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 = <span>(4/3)πr^3
so
mass = D (volume)
mass = 11.34 (</span>(4/3)π(5.5)^3 )
mass = 7902.96 g <span>Hope my answer would be a great help for you.

The answer is A. Working the formula backwards you get that r^2=256, so r=16
