find the circumference of the circle in terms of it.
671 cm
9 cm
1211 cm
3671 cm

C

Step-by-step explanation:

circumference of circle = 2*π*r

=2*π*6

=12π

sorry, i can't understand your question. will later if you describe more clearly!

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
