8

Step-by-step explanation:

The formula for the circumference of a circle is diameter times pi

Your equation should look like 50.24=dπ

To find d, you need to divide 50.24 by π: 50.24÷π≈16

The radius is half the length of the diameter, so divide 16 by 2 to get a radius of 8

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
