Calculate the area of a circle with the radius of 2cm. Pie=3

Fofino [41]

Answer:

Step-by-step 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
