Answer:

Area of a circle is πr²

where r is the radius

r = 7.29m

Area = π × 7.29²

= 166.957

= 166.96m² to 2 decimal places

Hope this helps you

What is the answer for the question down below
kotegsom [21]

Answer:

<h2>x = 45°</h2>

Step-by-step explanation:

If AC is a supplementary line, then

x + 90° + x = 180°

solution:

2x + 90° = 180°   |<em>subtract 90° from both sides</em>

2x = 90°    |<em>divide both sides by 2</em>

x = 45°

Find the zeros of y= x - 4x - 9 by completing the square.
Paraphin [41]

The zeros for the given equation are A. x = {2 \pm \sqrt{13}}.

Step-by-step explanation:

Step 1:

To solve for x in a polynomial equation, we use the formula

x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}.

Here a is the coefficient of x^{2}, b is the coefficient of x and c is the coefficient of the constant term.

In the given equation, a = 1, b = -4, c = -9.

Step 2:

Substituting the values of a, b, and c in the equation, we get

x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a} =\frac{-(-4) \pm \sqrt{(-4)^{2}-4 (1)(-9)}}{2 (1)} = \frac{4 \pm \sqrt{(16+36}}{2 }.

\frac{4 \pm \sqrt{(16+36}}{2 } = \frac{4 \pm \sqrt{(52}}{2 } = \frac{4 \pm2 \sqrt{(13}}{2 }= {2 \pm \sqrt{13}}.

So the answer is option A. x = {2 \pm \sqrt{13}}.
