Hey 20 points for the first person to show work and answer this

Step-by-step explanation:

First, the pizza is 18 inches in diameter, so

and, because the radium is half of the diameter,

Note that the units are inches.

Using the equation

where a is the area of a circle, we know that the area of the whole pizza is approx.254.5 square inches. Divide by 8 to find the area of 1/8 of a pizza. Each slice will have an area of approx. 32 square inches. For a precise result, the answer is

where a(s) is the area of a slice of pizza, and s is the total number of slices, given they are equal in size.

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.
