The circumference of a circle is 12pi. What is the diameter?

12

Step-by-step explanation:

The circumference of a circle is given as

Circumference = 2πr

Where; r is the radius of the circle

The diameter of a circle is 2 times the radius of that circle. It cuts the circle into 2 equal halves

Given, circumference of the circle = 12π

12π = 2πr

make r the subject by dividing both sides by 2π

12π/2π = 2πr/2π

r = 6

Diameter = 2r

= 2 X 6 = 12

  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.
