The correct answer would be B. A chord is a line inside the circle that is not divide the circle in half. I hope this helps!
Since in this problem, we are dealing with a balloon we can now say that the container or the shape we are dealing with is a sphere. The volume of a sphere is

hence the volume is directly proportional to the radius. The volume increase by a factor of
The answer is C. First, the area of the plot should be the multiplication of the two side lengths, so 11.7 * 15.4=180.18. However, we have to look at the significant digits to decide to what digit should we round the answer to. Since both 11.7 and 15.4 are accurate to the tenths digit, 180.18 should also be so, so we should round it to 180.2.
Answer:
Step-by-step explanation:
if you are going in a negative direction or by a decimal you are contracting, so the image would get smaller. If you are going in a positive direction(has to be a whole number as well) you have an expansion.
