Answer:
Independent Variable
Explanation:
The variables that are plotted on X-axis, the horizontal line of the graph are termed as independent variables. The variables plotted on Y-axis which is vertical side of the graph are dependent variables.
Compared to the frequency and wavelength of the radio signal emitted from
the antenna, the radio signal received by the astronauts has a (<span>1) lower frequency and a shorter wavelength.</span>
Answer:
Πr²(4r/3 - h)
Explanation:
Volume of a sphere is 4/3Πr³. If a hole of radius r is bored through, the hole with generate a circular shape in the sphere. The volume of the remaining portion of the sphere will be the difference between the volume of the sphere and the area of the hole bored(which will be volume of a cylinder since the hole bored will create a cylindrical shape in the sphere)
Area of the remaining portion = Volume of sphere - volume of a cylinder
Volume of sphere = 4/3Πr³
Volume of a cylinder = Πr²h
Volume of the remaining portion = 4/3Πr³ - Πr²h
= Πr²(4r/3 - h)
Where h is the height of the cylindrical hole
