I guess the function is a parabola with vertex at (0,0) and opens down so the range is (-infinity, 0].
B, 190.
First you find the area of the circle (pi times radius squared) however, since you are given diameter, you must find radius by dividing diameter by 2. So, your radius is 9, then you plug it into the formula and you get 254.5. After multiplying this by 0.75 because you only want to find 75 percent of the area, you get the answer of 191m
Answer:
144, would be your answer
Step-by-step explanation: Multiply 144 by 9 and you get 1296.
0.04 is multiplied 10 times to get 0.004
