What is the radius to 3cm

It is 6

Step-by-step explanation:

The radius is all the way around so all you have to do is multiply 3 times 2 which is 6

If r  is the radius of a circle, its area is given by  π× r 2

As radius is  3 c m , area is  π × 3 2

=  3.1416 × 9

= 28.2744 c m 2

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.
