Which set of ordered pairs represents y as a function of x? O {(3, 3), (3, 4), (4,3), (4,4)}
O {(2,-1), (4,-2), (6,-3), (8,4)}
O {(0,0), (1, 1), (1,0), (2, 1)}
O {(1,-5),(1,5), (2, -10), (2, -15)}

113.1

step-by-step explanation:

v=4

3πr3=4

3·π·33≈113.09734

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
