Find the area of the circle. Use 3.14 for .
80 yd
The area of the circle is about
yd2?

Step-by-step explanation:

A =nr²

=3.14 × (80/2)

=3.14 × 40

= 125.6yd²

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.
