What is the radius of a sphere that has a surface area of 12.56 in2? use 3.14 for pi. recall the formula sa=4 pi r 2?

  2087568668/1  

step-by-step explanation:

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
