Its 113.04 in63 after rounding = 113
Use the formula 4/3(pi)r^3
Answer:
First, I go by finding <em>x</em><em> </em>and <em>r</em>.
After that, put the numbers (ie. x= # and r=#) into the equations. Check it by finding L.H.S and R.H.S. (ie. left hand side and right hand side)
If you are still confused, comment down and I'll try to provide better explanation!
Answer:
perimeter of a regular hexagon=6×side length
side length in question is 'k'
perimeter=6×k=6k
You can factor this
x^2 + 10x + 16 = 0
(x + 8)(x + 2) = 0
so x + 8 =0 or x + 2 = 0
x = -8, -2
