Question
Find the volume of a sphere with the radius of 2 inches.
- 56.5 in³
- 26 in³
- 28 in³
- 33.5 in³
Hint:
Here, in this problem, the radius of the sphere is given. We are to find its volume and for this, we have to use the formula for calculating the volume of a sphere with a given radius. The formula for finding the volume 
of a sphere of radius 
is 
.
The correct answer is: 33.5 in³
Given that the radius of the sphere is 
inches.
We have to find the volume of this sphere.
We know that the volume of a sphere of radius is .
So, for inches, we get (put 
): 
.
Therefore, the volume of the given sphere is approximately 
.
Note that the value of 
is taken as 
which is an approximate value of . Though it is not exact, we can use this to find the value of a mathematical expression. We can take the value of as 
also.

Correct option is (d).
Reason ; In the given graph , on moving owards x axis from 1 to 4 there is change of there is change of 1.5 unit on y axis but on further movement from point 4 to 8 there is small change of .5 units on y axis .it shows that there is very small and non constant change on y axis hence the graph shows non linear realtionship

Mrs. Collins made a scatterplot to show the relationship between the number of absences and a student’s final exam score. Based on this scatterplot, a student with 6 absences should get approximately ___________ score on the final exam?
A trendline is a line drawn over pivot highs or under pivot lows to show the prevailing direction of price. Trendlines are a visual representation of support and resistance in any time frame. They show direction and speed of price, and also describe patterns during periods of price contraction.
