Answer:
65.12 mm
Step-by-step explanation:
Circumference of semicircle = 8π mm
Perimeter = (40 + 8π) = 65.12 mm

Given inequality
=> −2(x+1)≥3x+8
=>

now multiply with - on both sides.
As we know now sign will change
=> 5x >_ -10
Now divide by 5 on both sides
=> x >_ -2

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

Step-by-step explanation:
2nd qestions explanation
put value of x=2 in equation as x-2=0 from equation
(2)^3-6(2)^2+a2+10=2
8-24+a2+10=0
2a=-18+24
2a=6
a=3
