Answer:
50
Step-by-step explanation:
Here, we need to find the area of a circle.
So, area of a circle = πr²
= 3.14 * (10, 000)²
= 3.14 * 100,000,000
= 314,000,000 ft²
In short, Your Answer would be Option A
Hope this helps!
Answer:
Step-by-step explanation:
Total bill - the tax = cost of 3CD's
Our total bill is $35.40, the tax is $2.70, therefore,
35.40 - 2.70 = cost of 3 CD's so
3 CD's = $32.70
Divide that by 3 to get the cost per CD:
32.7 / 3 = $ 10.90 per CD
To complete the square:
1) Move the "non-x" term to the right.
It's already there.
2) Divide the equation by the coefficient of x^2.
It's already done. Coefficient of x^2 is 1.
3) <span>• take the coefficient of X
this is -2
• divide it by 2
-2 / 2 =-1
• square that number
-1^2 = 1
• then add it to both sides of the equation.
x^2 -2x = 24
x^2 -2x +1 = 25
</span>
<span>4) take the square root of both sides of the equation (remember that each square root has TWO solutions).
</span>
<span>Taking the square root of
x^2 -2x +1 = 25
equals
(x -1) = 5 AND
</span>
<span>(x -1) = -5
So, x = 6 and
x = -4
