Answer:
Part 1) The volume of the ball is 256 cm³
Part 2) The radius of the ball is 3.94 cm
Step-by-step explanation:
Part 1) we know that
The density is equal to divide the mass by the volume
D=m/V
Solve for the volume
The volume is equal to divide the mass by the density
V=m/D
In this problem we have
m=128 g
D=0.5 g/cm³
substitute
V=128/0.5=256 cm³
Part 2) what is the radius of the ball?
we know that
The volume of the sphere (ball) is equal to
we have
assume
substitute and solve for r

at least I know one of the anwsers
Based in your question that ask to evaluate the integral of tan^2(x)sec(x), base on my calculation and the use of the integral procedures and formula i came up with a solution that could answer your question and the evaluated answer is <span>tan(x)sec(x)−∫(<span>sec2</span>(x)−1)sec(x)dx</span>
Answer:
x<6
Step-by-step explanation:
the open circle on the line does not include 6. the arrow pointing away from 6 going toward lower numbers means that x is less than 6.
Answer:
r = 18m
Step-by-step explanation:
h = 50 m
Volume of cone = 5400π m³
r = 18 m
