A is the answer i think :)
<u>Given</u>:
The graph shows the speed of a ball in free fall for 10 seconds.
We need to determine the constant of proportionality for the given graph.
<u>Constant of proportionality:</u>
The constant of proportionality can be determined using the formula,
Where k is the constant of proportionality.
Let us consider any of the coordinate from the graph and substitute in the formula.
Consider the coordinate (4,40) and substitute in the above formula.
Thus, we have;
Thus, the constant of proportionality is 10 meters per second squared.
Answer:
r = 18.8
Step-by-step explanation:
We use the circle sector area formula and solve for the radius.

Answer:
1017 square ft.
Step-by-step explanation:
pi x r x r x h
3.14 x 6 x 6 x9 =1017.36
rounding to the nearest whole number, the answer is 1017 square feet
