The residual plot for a data set is shown. Based on the residual plot, which statement best explains whether the regression line
is a good model for the data set and why?
A.)The regression line is not a good model because there is no pattern in the residuals.
B.)The regression line is not a good model because only one point in the residual plot is on the x-axis.
C.)The regression line is a good model because the points in the residual plot are close to the x-axis and randomly spread around the x-axis.
D.)The regression line is a good model because the residuals approach 0 as x increases.

Answer:
972π or 3052.08 if π=3.14(remember to label the answer with your units)
Step-by-step explanation:
The formula for the volume of a sphere is π
. So, just plug the radius into the formula.
<em> </em>in this case is
which is 729. For,
×729, the 3 and 729 cancel out to create 4×243 which is 972. Just add π to this and you get 972π. If π is 3.14 just multiple 972 and 3.14 to get 3052.08.
