Spherical ball of lead has a diameter of 5.5 cm . what is the mass of the sphere if lead has a density of 11.34 g/cm3? (the volu
me of a sphere is (43)πr3 where r is the radius.)
1 answer:
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.

Well the first part is 27 but the second part is adding 60 to 21 which is 81. dont forget that!
Hey there!
2x+1=73.
2x=72.
x=36<span>.

So the 2 consecutive numbers are 72 and 36!
Hope this helps! :)
Answer:
the answer is " the slope of the function A is less then the slop of the function B
hope it helps
Answer:
The answer is A, 50°.
Here, angle CAB= 60°.
In triangle ABC,
60°+70°+ angle ABC= 180°.
angle ABC= 50°.
