Step-by-step explanation:
(5)
Using the trigonometric identity
sin²x + cos²x = 1 ⇒ cos²x = 1 - sin²x
Given
3sin²Θ + 2cos²Θ - 2
= 3sin²Θ + 2(1 - sin²Θ) - 2
= 3sin²Θ + 2 - 2sin²Θ - 2
= sin²Θ
(6)
Using the trigonometric identity
secx = 
Consider the left side
= 
= = secx = right side ⇒ verified
(7)
Using the trigonometric identity
1 + cot²x = csc²x
Given
sin²x. cot²x + sin²x ← factor out sin²x from each term
= sin²x(cot²x + 1)
= sin²x. csc²x
= sin²x × 
= 1
Hey there! I'm happy to help!
The area of a circle is the radius squared multiplied by pi (we will use 3.14). We already have the area, so we will go backwards.
1441÷3.14≈458.9171975
We find the square root.
√458.9≈21.42235275
Now we have our approximate radius. The diameter is twice the radius.
21.42235275×2=42.8447055
I don't know exactly if they want you to round it or not, but the diameter is somewhere around there.
Have a wonderful day! :D
