Answer:

C = 2pi mm or approximately 6.28 mm

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi * r

C = 2 * pi *1

C = 2pi

We can approximate pi by 3.14

C = 2*3.14

C =6.28 mm

Answer:

The circle's circumference is 2 pi ml

Step-by-step explanation:

The formula for the circumference of a circle is 2\pir, or diameter times pi.

In this case, we simply plug into the equation. Using the formula 2\pir, we get 2(1)\pi, or 2\pi ml

ira [324]

Answer:

Check below for a lucid explanation.

Step-by-step explanation:

The independent variable is the variable whose variation does not depend on another external variable. It is the variable on the x-axis which in this case is the growth of the baby.

Note: The diagram you attached to this question does not include the calibration on the x - axis which will give us the independent variable at point

This, nevertheless, is a very simple task. Locate the point A on the graph and trace it downwards to the x - axis, the value written where the line coincides with the x -axis is the value of the independent variable( growth of the baby) at point A.

SIZIF [17.4K]
Solutions 

To convert 2/14 into lowest terms you have to divide by the greatest common factor. The greatest common factor of 2 and 14 is 2. 

2 ÷ 2 = 1 
14 ÷ 2 = 7 

1/7 is in lowest terms
