Answer:
6
Step-by-step explanation:
The center of the circle is the midpoint of the diameter. The midpoint can be found by averaging the coordinates of the end points:
((-4, 2) +(12, 10))/2 = ((-4+12)/2, (2+10)/2) = (4, 6)
The y-coordinate of the center is 6.
First, determine the width of the court by dividing the area by the length.
width = area / length
width = 162 m²/18 m = 9 m
Then, determine the perimeter of the court by the equation
P = 2L + 2W
where L and W are length and width, respectively.
P = 2(18m) + 2(9m) = 54 m
Given that every 20 m roll of tape costs $2.79, and even if the court is only 54 m, Jeff still needs to buy 3 20-m roll
total cost = ($2.79) x 3 = $8.37
Thus, the answer is letter B.
