I'm probably wrong, but thats how I understood the question.
Answer:
4608*sqrt(3)
Step-by-step explanation:
x + 2x = 3x, so 3x is the height of the triangle. This is a 90-60-30 triangle so the base would be 3x*sqrt(3). To find the area, we can multiply the base with the height and divide by two, so it would be (3x)(3x*sqrt(3))/2 or (9/2)x^2 * sqrt(3). x = 32, and plugging this into the equation gets us to (9/2)32^2 * sqrt(3), which is 4608*sqrt(3).
Answer: 3900
ft^3
if you use the formula on how to find the volume of a cone
V=r^2*h/3
you will insert 30 where the r is, 13 in where h is, after you just solve that and your answer would be 3900 ft^3
