Answer:

12.56 cm

Explanation:

Area of a circle is A=3.14 r to the second power.

so the radius is 2 cm. I would do 2 x 2 and that equals ,4 next 4 x 3.14= 12.56

i don't know what pie=3 means but this is my answer from the best of my ability.

Answer:

12

Explanation:

The formula to find the area of a circle is:


\pi
r^(2)

Where "r" is the radius of the circle.

In this case, the radius is 2, and as per what is given in this problem (what the problem asks one to use), pi is rounded down to 3.

The equation will be:

3 * 2^2

Simplify, remember the order of operations:

3 * 4
