Formula is pie radius-squared
Radius= 1/2 of diameter
Radius = 7
Formula = pie- 7 squared
Or as the question says
Pie= 3.14
3.14 multiply by 7 squared
= (A) 153.86 yards squared
1.40 x 21 passes = 29.40 for passes.
38.40 - 29.40 = 9.00

Answer:
Domain is all real numbers, and range is all numbers greater than or equal to -2. If thee was anything you didn't understand let me know.
Step-by-step explanation:
The domain is what x values work, or it may be better to say the horizontal axis. is there any number you cannot use? if you cannot tell, this is a parabola, like x^2. Is there any number you cannot plug into x^2. The answer is no, the domain for all parabolic functions is all real numbers.
The range you really want to look at visually here. Range is y values you can get, or values on the vertical axis. I would also compare it to x^2 again. You should know you can make it as high as you want, here is the same. but at -2, there is no point below that. so the range is -2 and up
The other options are just specific numbers. you can disprove those by choosing a number not on their lists. For the domain literally any other number. For range any number not on the list greater than -2
