Minus 14 from both sides
x²-4x-14=0
use quadratic formula because we cant factor
for
ax²+bx+c=0
so
1x²-4x-14=0
a=1
b=-4
c=-14
the solutions are
x=2+√3 and
x=2-√3
x²-4x-14=0

For this case we can find the volume and area of the cone:
Where:
V: It's the volume
A: It's the radius of the base
h: It's the height
We have to:
Substituting:
On the other hand, the area of the cone is given by:
Where:
A: It's the radio
g: It is the generator of the cone.
