f the points (-4, 1) and (2, 1) are the endpoints of a diameter of a circle, where is the center? A) (-7, 1) B) (-1, 1) C) (1, - 1) D) (5, 1)
1 answer:
Answer:

3 x 3 x 3 x 3
3 x 3=9
3 x 3=9
9 x 9=81
Answer:
so you would actually multiply 32 x 15=480 then subtract 480 - 384= it would have 96 miles left. then divide 96/32= 3
so your answer would be 3 gallons left
Step-by-step explanation:
The volume of cylinder formula is πr²h. V = π(12)²(9) V = 1296π³ So the correct answer is 1296π³
Answer:
Since a and b = (a, b) = (x, y) have the same sign.....P will lie either in the 1st quadrant of the Cartesian plane or the 3rd quadrant of the Cartesian plane.
