Acircle with a radius of 9cm sits inside of a circle with a radius of 11cm. what is the area of the shaded region? round your answer to the nearest hundredth. due tomorrow

Step-by-step explanation:

The complete question is

The area of the shaded region is the area inside the larger circle and outside the smaller circle

so

To find out the area of the shaded region subtract the area of the smaller circle from the area of the larger circle

Remember that

The area of the circle is

therefore

The area of the shaded region is

where

---> radius of the larger circle

---> radius of the smaller circle

assume

substitute

look a the sides they are perpendicular

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.
