Answer:

153.86 un²

Step-by-step explanation:

Area circle = πr²

Radius is the distance of the center to the edge(perimeter)

Radius = 7

Area circle = 3.14(7)²

Area circle = 3.14 * 49 = 153.86

<h2>Solving for the Area of a Circle</h2><h3>Answer:</h3>

The area of the Circle $A$ is approximately $153.86$

<h3>Step-by-step explanation:</h3>

The area of a circle, $A_{\circ}$ , is calculated by $A_{\circ} = \pi r^2$ . We can see that the distance between point $A$ to any point on the circle is $7$ . This means that $7$ is the radius of the circle.

Solving for $A_{\circ}$ :

$A_{\circ} = \pi r^2 \\ A_{\circ} \approx 3.14(7)^2 \\ A_{\circ} \approx 3.14(49) \\ A_{\circ} \approx 153.86$

Answer:

$x^2-4x+3$

$63\ \text{sq. units}$

Step-by-step explanation:

l = Length = $\dfrac{x^2-x-6}{x-5}$

w = Width = $\dfrac{x^2-6x+5}{x+2}$

Area is given by

$A=lw\\\Rightarrow A=\dfrac{x^2-x-6}{x-5}\times\dfrac{x^2-6x+5}{x+2}\\\Rightarrow A=\dfrac{x^2-3x+2x-6}{x-5}\times\dfrac{x^2-5x-1x+5}{x+2}\\\Rightarrow A=\dfrac{(x-3)(x+2)}{x-5}\times\dfrac{(x-5)(x-1)}{x+2}\\\Rightarrow A=(x-3)(x-1)\\\Rightarrow A=x^2-4x+3$
