You multiply the two side lengths for area
To get 52x^3y
To find perimeter you add all the side lengths to get 8x^2+26x
I honestly think it has two solutions
X=-1
X=6
A. because of 1x4=4 then 8x2=16
If the radius of the cone is 9 inches,
then the volume of the cone is
(81 pi) x (the height of the cone, inches) cubic inches
