1-A 2-B I believe is the right answers
Assuming you meant square root of 90 it would be
90 equals 3 times the square root of 10
√90 = 3√10
V= πr^2xh
π=3.14
r=6ft
h=8ft
V=3.14x6^2x8=3.14x36x8=904.32ft^3
From the data shown in the scater plots, the points are scattered apart which means that r is not close to 1.
Also the data points increase to the right which means that r is positive.
Therefore, the estimate for r in the data shown in the scatter plot is 0.55
