Answer:
cos 225° =
sin 225° =
tan 225° = 1
Step-by-step explanation:
I cannot sketch a diagram, but a 225° angle is a 3rd quadrant angle and the reference angle is 45° (225 - 180 = 45)
cos and sin are negative in the 3rd quadrant and the tan is positive
cos 225° = - cos 45° =
sin 225° = -sin 45° =
tan 225° = tan 45° = 1
Answer:
The answer is all real numbers
Step-by-step explanation:
4(x + 2) = 4x +8
Distribute the 4:
4x + 8 = 4x + 8
Then subtract 4x and 8 from both sides
0 = 0
This statement is true so its all real numbers
Answer:
Hence the volume of the cone is 31384.52 cubic feet
Step-by-step explanation:
We must first need to understand how the volume of a cone is calculated.
It is simply calculated by multiplying the base area of the cone by the height, and dividing the result by 3.
This is :
Volume of cone =
we are not given the base area of the cone. However, we are given the circumference from which we can get the radius of the base.
Circumference =
hence the volume of the cone is
Hence the volume of the cone is 31384.52 cubic feet
