The diameter of a round rug is 42 inches. What is the approximate area of the rug?

441 inches squared i think

Step-by-step explanation:

radius = 42/2 = 21 inches

area = x

area = 441

area = 1385.44236

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
