Answer:

Option C is correct.

Step-by-step explanation:

We have been given the diameter of circular flower bed.

Radius=\frac{diameter}{2}

Radius=\frac{10}{2}=5

Area of circle is \pi\cdot r^2 where r is the radius of circle.

So, we will substitute values in the area of circle to calculate the value of area of circular flower bed.

Area=\pi 5^2

\Rightarrow Area=25\pi

Therefore, option C is correct.

-2x^2-8x=4

divide by negative 2

x^2+4x=-2

complete the square

(x+2)^2=-2+4

(x+2)^2=2

x+2=±\sqrt{2}

x=-2±\sqrt{2}

    +1  +1

(the -1 cancels out)

5x=15

(divide by 5 on both sides)

x=3
