Hey there!
1.) let's remember that a acute angel is very tiny, it is less then 90 degrees. So we would want to find one of your options that would be very small.
46 would seem to be the answer.
x=46
Hope this helps you.
Answer: I'll help you, but where is the question?
Step-by-step explanation:
The radius of your cone is half of 18 units = 9 units.
The volume of any cone is <span><span>V = (1/3) · (pi) · (radius)² · (height) </span>
</span>
-- Take that formula for the volume of any cone.
-- Write '8' in place of 'height'.
-- Write '9' in place of 'radius'.
-- Write '3.142' in place of 'pi'.
-- Complete the arithmetic.
-- Bada-bing, you've got the volume.
