Answer:
here what to do
Step-by-step explanation:
Since the volume of a cone is pi the radius squared times the height divided by 3. If you know the diameter,you simple divide by 2
Answer:
x = 14
Step-by-step explanation.
First I would use sine to find x's value. So ----> sin(30) = 7/x ----> x sin(30) = 7 ----> x = 7/sin(30) = 14.
You Can also find that x is equal to 14 by applying the 30, 60, 90, triangle rule. Becuase '7' opposes the 30 degree angle it is 1/2 the hypotenuse, if thats the case just multiply the 7 by 2 and you have the hypotenuse length.
I think it’s the second one because The formula would be
x=
2a
−b±
b
2
−4ac
