Evaluate B ^2 for B = -4.

1 answer:

4 0

B^2 = what when B = -4

Note: B^2 means B square or B to the second power. The power, in this case 2, tells us how many times to multiply the base B by.

So, B^2 = B • B.

Replace B with -4.

(-4)^2 = (-4)(-4) = 16.

We conclude by saying that B^2 = 16 when B is - 4.

Note: The answer is the same when B is 4.

Dennis_Churaev [7]

Answer:

$A=4r^{2}-r^{2}\pi$

Step-by-step explanation:

1. To calculate the area of the grass you must substract the area of the square and the area of the circle.

2. The area of the square is:

$A1=L^2$

Where $L$ is one side of the square.

3. You have that:

$L=2r$

4. Therefore:

$A1=(2r)^{2} =4r^{2}$

5. The area of the circle is:

$A2=r^{2}\pi$

6. The are of the grass is:

$A=4r^{2}-r^{2}\pi$
