The diameter of a circle is 3 m. Find its area to the nearest tenth.

7.1

Step-by-step explanation:

area of a circle is pi times the radius squared

so divide the diameter by 2 to get the radius

then thats 1.5 so square that then multiply by pi

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.
