Aregular hexagon is inscribed inside a circle. the perimeter of the hexagon is 90 units. a. what is the approximate measure of the radius of the circle? b. what is the approximate area of the circle?

a The center of the hexagon and of the circle are the same point. Also length of one side of the hexagon = 90/6 = 15 units.

If we join each vertex of the hexagon to the center then we get 6 equilateral triangles (because internal angle of reg hexagon = 120 and vertex angles of the triangles = 60) so the radius = length of side of hexagon = 15 units (answer)

b Area = pi * 15^2 = 706.9 units^2 to nearest tenth. Answer

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
