Answer:
Theta=1.57rad, 4.71rad, 0rad, 2π rad, π rad and –π rad
Answer:
14km
Explanation
11km + 11km = 22km is the sum of both the width.
If you want to find the length than minus the perimeter with 22.
50km - 22km = 28km is the sum of both the length.
To know only one side of the length, divide it by 2.
28km/2 = 14km is the length
Answer:
4π ≈ 12.5663706144
Step-by-step explanation:
The circumference of a circle is 2πr, or 2*pi*radius
Suppose the circle has a diameter of 4 inches. A diameter is 2x the radius, of which we are looking for, therefore:
4÷2=<u>2 inches</u> (radius length)
Now that we have the radius, let us <u>substitute</u> to find the circumference:
2πr=
2π2=
4π≈
<u>12.5663706144</u>
<u></u>

Answer:
( cos40° + isin40°)
Step-by-step explanation:
To divide

=
[ cos(x₁ - x₂) + isin(x₁ - x₂)
Given

=
( cos(90 - 50)° + isin(90 - 50)°
=
( cos40° + isin40° )
