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

12

Step-by-step explanation:

The formula to find the area of a circle is:

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

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
