Answer:
40287600 = B. 4 x 
Step-by-step explanation:
<u>We first have to do the multiplication of the numbers given:</u>
19 * 2,120,400
=> 40287600
<u>Now we have to figure out how many digits are after the number 4:</u>
4, 0 2 8 7 6 0 0
7 digits
Meaning that we need an exponent of 7 for it to be in scientific notation, giving us with the answer B. 4 x
Area of the square is 144m.
Area of the circle is 113.1m.
Subtract A of circle from A of Square which equals 30.9meters. That is your answer.
If you want I can teach you step by step just comment if you want me to...
Well if you have three and add negative 3 it equals 0
Consider the absolute value, because we only worry about the quadrant later.
Thus, we know that the hypotenuse has a length of 4 units, and the side opposite the angle, A is √3, because this is the nature of the sine function in relation to its triangular component.
The missing side can be found using Pythagoras' Theorem:
4² - (√3)² = x²
16 - 3 = x²
13 = x²
x = √13
Since angle A is in the third quadrant, the tangent function will produce a positive angle.
