That what i got. hope that help
<span>An equilateral triangle has an Area = (1/2) a^2 sqrt3
The base has an equation x^2+y^2 =9
So at x , y= sqrt (9-x^2)
The side of the triangle is a= 2y
So dVolume = (1/2)a^2 sqrt3 dx
dV= (sqrt 3) (9-x^2) dx
V= sqrt3 INT (9-x^2) dx
-3<x<3
by simmetry ,
V= 2sqrt3 INT (9-x^2) dx
0<x<3
V= 2sqrt3 ( 9x-x^3/3)
V= 2sqrt3 ( 27-9)
V= 36 sqrt3 ANSWER
Hope This Helped! :3</span>
I think that the answer is a) it could also be d)
i'm sorry if I'm wrong i hope this helps tho :)
Idk . there is no following
