Its C , a negative association because it is going from the top left to the bottom right which is knows as a negative association/negative correlation , hope this helps
Yes

Given:
The circumference of the base of a cone is 10π cm.
The circumference of the base of a second similar cone is 20π.
To find:
The ratio of the surface area of the first cone to that of the second cone.
Solution:
Let the radii of base of two cones are and respectively.
Circumference of the circular base is , where, r is radius.
We have,
And,
It two cons are similar, then ratio of there areas is equal to square of the ratio of there corresponding dimensions, i.e., radius or heights.
The ratio form is
Therefore, the ratio of the surface area of the first cone to that of the second cone is 1:4.
Answer:
171.9 degrees.
Step-by-step explanation:
The factor is 180/π.
So 3 radians = (3*180)/π
= 171.9 degrees.
