Answer:
sin²x
Step-by-step explanation:
we have
(1 − cos x)(1 + cos x)=1-cos²x
Remember that
sin²x+cos²x=1 ------> i-cos²x=sin²x
therefore
(1 − cos x)(1 + cos x)=sin²x
Step-by-step explanation:
As you have done till
3p + 8 = 20
3p = 20 - 8
3p = 12
p = 12 / 3 = 4

Answer:</h3>
The Area of the tray ≈380 cm
<h3>
Solution:</h3>
- We are given the diameter of the tray, which is equivalent to 22 cm.
- We are asked to find the area of the tray.
- Remember the formula:
- Area of a circle = πr²
- Where
- π -> pi (3.14...)
- r -> radius
- Notice that we aren't given the radius. We're given the diameter only.
- No reason to panic. We can easily find the radius by dividing the diameter by 2.
- The radius is equal to 11 cm.
- Now, plug the values into the formula:
- A=π(11)²
- A=121π
- A≈380 cm
