Answer 2

15.57 looks good!

Answer 4

@ganeshie8 would you consider that simplest radical form? or is my answer good like that?

Answer 5

definitely not
i can't help because i do not know what the radius of a triangle is, but my guess is this has been cooked up so that you get something simple
in any case not decimal form

Answer 6

equilateral triangle is a regular polygon
for regular polygons, radius is defined as the distance between center and any of the vertices

Answer 7

the radius is \[2\sqrt{3}\]

Answer 8

is there an easy formula for the area given the radius or do we have to start from scratch?

Answer 9

I have to solve for the area using (1/2) * (apothem) * (perimeter)

Answer 10

i am so ignorant of geometry i should shut up, but i am almost 100% positive that the answer you got as a decimal is not in simplest radical form
