Area of a circle= πr²
Data:
diameter=11 in
ratius=diameter/2=11 in/2=5.5 in
Area of this circular plate=π(5.5 in)²=30.25π in²=30.25 * 3.141592... in²≈
≈95.0 in².
answer : c 95.0 in²
The answer is 54in i belive
The values would be
sin2x = -3/5
cos2x = -4/5
tan2x = 3/4
What are double angles in trigonometry?
The double angle formulas are used to find the values of double angles of trigonometric functions using their single angle values. For example, the value of cos 30° can be used to find the value of cos 60°. Also, the double-angle formulas can be used to derive the triple-angle formulas.
Given: tanx = -3
Now as we know,

Now

And similarly, we can find the value of tan2x, as
tan2x = sin2x/cos2x
= (-3/5)/(-4/5)
= 3/4
Hence,
The values would be
sin2x = -3/5
cos2x = -4/5
tan2x = 3/4

Answer:
$8.11
Step-by-step explanation:
Original Price: $16.95
Discount: 54% Decimal Form: .54
Tax: 4% Decimal Form: .04
Let's start with the discount...
16.95 x .54 =9.153 Round = 9.15
16.95 - 9.15=7.80
Now, for the tax..
7.80 x .04=0.312 Round = 0.31
7.80 + 0.31=8.11
Hence. the Selling price is $8.11
