What is the circumference of a circle with a diameter of 12 cm use 3.14 for r !

C = 2πr or πd

Since the diameter is given, we will use C = πd.

C = π×12

C = 37.68 cm

The answer is C = 37.68  or    C ≈ 37.7

Circumference of a circle is found by using 2πr:

π = 3.14

diameter = 12      so          radius = 12/2 = 6cm

2×3.14×6

= 6.28×6

= 37.68

≈ 37.7

d. 9

step-by-step explanation:

in the table given in the picture, x is the input of the function and f(x) is the output on the given input. in the given table, it can be read as the value of function at -3 is it's respective value of f(x) which is -9.

as we have to find the value of f(3), we will see that what is the value of output on input 3. we can see in the table that the output value at x=3 is 9.

so, option d is the correct answer ..
