Answer: 3.2t - 2.4
Step-by-step explanation:
Since this is a polygon with 6 sides, it has a total of 720 degrees.

So adding together all the angles, you get:
(2x-50) + (x+40) + (x+20) + x + 150 + 80.
Simplify.
5x+240. And since you know all the angles add up to 720 degrees, set it equal to each other.
5x+240 = 720
5x= 480 (720-240)
x= 96
Finally, plug in x to get the rest of your answers.

Answer:
Step-by-step explanation:
The formula of a volume of a cone:
r - radius
H - height
We have
r = (7 : 2) in = 3.5 in
H = 4 in
Substitute:
B 1/4 because 12/3 equals 4 so she only gave 1 of the 4 she had so the answer would be 1/4
