Answer:
-2496
Step-by-step explanation:
The value of Sin(a) suppose that Cos B = 0.68 in which case, a + B = 90° is; 0.68.
<h3>Trigonometry</h3>
First, when we have two angles, whose sum equals, 90°.
In essence, Since the algebraic sum of angles A and B is 90°;
By trigonometric identity;
Where; (90 - A) = B.
Therefore; Sin A = Cos B = 0.68.

To start off you need to figure out how much money each item costs. Now get out your calculator because it will make this process go much faster.
EXAMPLE:
If your sodas cost $2.25 EACH you need to do the following math equation
2.25 X 3 = 6.75 witch is the total you would be paying in this situation.
HOT DOGS EXAMPLE:
Lets say that your hotdogs are $4.75 PER DOG. You just need to follow the same steps above.
4.75 X 2 = 9.5 but thats not how we write money so it would be $9.50
Hope this helps,

Answer:
A) 113 m²
Step-by-step explanation:
Use the formula for area of a circle.
Area of a circle = πr²
π = pi = 3.14 (rounded)
r = radius
² = the power of 2, or the radius (in this case) multiplied by itself.
Note that the radius is given, and it is 6. Plug in 6 for the radius:
A (circle) = π(6)²
First, solve the power. Multiply 6²:
6² = 6 * 6 = 36
Next, multiply 36 with π (3.14):
36 x 3.14 = 113.04
A) 113 m² is your closest answer.
