If a semicircle is rotated about the x axis of the graph then the resulting three dimensional shape will be a sphere.
Given a semicircle on a graph.
A semicircle is a half circle .A sphere is a geometrical object that is a three dimensional shape , It is the set of points that are all at the same distance r from given point in three dimensional shape.
Rotation is basically an action of rotating around an object or an axis.
If a semicircle is rotated about x axis then the resulting figure will be a sphere. This is because of the fact that when the semi circle is rotated about the x axis then all the points will be at equal distance in all directions from the center.
Hence if a semicircle is rotated about x axis then the resulting figure will be a sphere.

Answer: The answer is in the 1st image.
Explanation: The explanation is in the 2nd image.
Answer:
answer is 5 centimeter...
You measure your height and the height of your shadow the you measure the height of the poles shadow and you then have the equation
y(your height)/s(your shadows height)=x(flagpoles height)/z(flagpoles shadow)
then to find the answer you just multiply the z by y/s
