153.9 in²

Step-by-step explanation:

Using the formula: A = π r²

Where r = the radius and π is 3.14.

The radius is the diameter divided by 2.

14 divided by 2 is 7.

Plug in 7 into the formula:

A = π 7²

7² is 49.

49 times π is equal to 153.86.

Rounding this up to the nearest tenth, you'll get 153.9

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.
