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:
x = 7
Step-by-step explanation:
First, multiple both sides by 5:
x + 3 = 10
Then, subtract both sides by 3:
x = 7

Answer:
a) (2.64 -2/9 -0.35 +5/8)/4
b) perform the sum, then the division, then round as needed
Step-by-step explanation:
a) The average of a number of items is their sum, divided by the number of items. Here, we want the average of 4 changes, so we compute it as the sum of the changes divided by 4.
average change = (2.64 -2/9 -0.35 +5/8)/4
__
b) My calculator is capable of adding these numbers directly. For a result rounded to the nearest hundredth, it can be a good idea to represent the fractions using at least 3 decimal digits.
So, the steps would be ...
- convert fractions to their decimal equivalents, using 3 decimal digits
- add up the values
- divide by 4
- round to hundredths
Performing these steps, we get ...
average change = (2.64 -0.222 -0.35 +0.625)/4 = 2.693/4
average change ≈ 0.67 . . . degrees
The average daily temperature change of a city was 0.67 degrees.
