Where's the graph at? Did you forget to place?
Answer: figure 1). x = 36 2). x = 123
Explanation:
Figure 1:
Angle x = angle 1
And angle 4 = 4x
Angle 4 + angle 1 = 180
4x + x = 180
5x = 180
x = 36
Figure 2:
Angle 1 = 68 degree
Angle 2 = 55 degree
Find angle 3:
180 - (68 + 55)
= 180 - 123
= 57 degree
But angle 3 = angle 4 = 57 degree
But: angle 4 + x = 180
57 + x = 180
x = 180 - 57
x = 123
Hi!
Let's find the volume of the cylinder first.
The equation to find the volume of a cylinder is
(r = radius, h = height)
v = πr²h
Fill in the values
v = π · 100² · 250
Solve
v = π · 10000 · 250
v = π · 2500000
v = 7853981.63
Now since the cylinder is half-full, divide by 2.
7853981.63/2 = 3926990.81
To find how many liters are in the container, divide
1 liter = 1000
3926990.81/1000 = 3926.99081
Round to the nearest liter
3927
There are 3927 liters in the cylindrical tank
Hope this helps! :)
Part a: hexagon is a six sided polygon.
Part b: dodecagon is a 12 sided polygon.
Part c: decagon is a 10 sided polygon.
Explanation:
Part a: The given polygon consists of 6 sides.
Hence, a polygon with 6 sides is called as hexagon.
Part b: The given polygon consists of 12 sides.
Hence, a polygon with 12 sides is called as dodecagon.
Part c: The given polygon consists of 10 sides.
Hence, a polygon with 10 sides is called as decagon.
