False wanna know why?
x^2 - 2 = 2
has integer coefficients
but the solutions are not integers
Answer:
50.28 cm
Step-by-step explanation:
r= 8cm
Circumference=

=

=50.28cm
The surface area of the regular hexagonal pyramid is
SA = (1/2) pl + B
where p is the perimeter of the base, l is the slant height of the pyramid, and B is the area of the base
The area of a regular hexagon is 3 sh
where s is the length of the side and h is the length of the apothem.
So,
SA = (1/2)(6)(12) (11) + 3(12)(6sqrt3)
SA = 770 square meters
