-9v-6+7v=6
-2v-6=6
-2v=6+6
-2v=12
v=-6
The smallest angle would be 16.26°, with the other angles being 90° & 73.74°
Could u give the rest of the question?
The formula for the volume of a cone is V=(1/3)πr^2h.
To find r (radius) divide the diameter by 2, giving you 2.5 cm.
Plug in the numbers now !
V=(1/3)(3.14)(2.5^2)(9)
V=(1/3)(3.14)(6.25)(9)
V=(1/3)(176.625)
V=58.875
Therefore, the volume of the cone is about 59cm^3 :)
What problems do you need help with I dosen't show???
