I believe the area of that polygon is 473 square feet because to find the area of the odd corner you have to look at the differences between the different side lengths, so 2*5=10 and then you have to divide 10 by 2 because only half of that corner is there.

The answer she has is not correct.
All the steps she did are correct, except they forgot to convert the decimal answer into the proper percentage by multiplying it by 100.

The correct answer should be 0.125 * 100 = 12.5%

What is the equation of the circle with center (4, 4) that passes through the point (10, 14)?

Katarina [22]

Answer:

Step-by-step explanation:

You use the given information in the standard form of a circle equation to solve for r. We have (h, k) which is the center and a point (x, y). The standard equation for a circle is

$(x-h)^2+(y-k)^2=r^2$

Filling in:

$(10-4)^2+(14-4)^2=r^2$ and

$6^2+10^2=r^2$ and

$r^2=136$

Now that we used the coordinate we don't need it anymore. x and y go back into the equation as x and y, not numbers. We do, however, need the center. Writing the equation:

$(x-4)^2+(y-4)^2=136$ which is choice D.
