the formula for the volume of a cone is v=1/3 pi times r squared h where v represents the volume, r represents the radius of the
base, and h represents the height. what is the height of a cone with a volume of 66 cubic centimeters and a base with radius of 3 centimeters

Alright so
Surface area = (width x height) + (length x width) + (length x height) + (length x side)
Surface area = (width x height) + (length x width) + (length x height) + (length x side)
We have that
2sin²<span>x - sinx - 3 = 0
</span>
Let
A------> sin x
so
2A²-A-3=0
using a graph tool-----> to resolve the second order equation
see the attached figure
the solutions are
A=-1
A=1.5------> is not solution because sin x <span>can not be 1.5
the solution is
A=-1
therefore
sin x=-1
x=arc sin(-1)=-90</span>°
the answer is
sin x=-1
x=-90° or 270°
