Answer:

254.34

Step-by-step explanation:

The area of a circle = pi * r^2 where pi = 3.14 and r = radius of the circle, which is the length of any line drawn from the center of the circle to the circle’s edge.

The diameter of a circle is the distance of a line from one point on the edge of the circle to another point on the edge of the circle, passing through the center. It’s the longest line you can draw from one edge of a circle to another edge. It is equal to 2r.

So here, 2r = 18 and r = 9. Therefore, we plug the value for r into the area equation above and get:

A = pi * r^2 = 3.14*(9^2) = 3.14*81 = 254.34

The center of the dilation is the origin, and the scale factor is 2.

To find the coordinates of the points under this transformation, it is enough to multiply both coordinates of the points X, Y, and Z by 2.

Take a look at the dilation of point Z. To get to Z', both the x and y coordinate of Z must be multiplied by 2.


So, the coordinates are:

X'(8, 0); Y'(6, 4); Z'(4, -4).

Simple interest is basically the cost of borrowing money over a period of time.  So if you have borrowed $110.00 at 5% for two years, you will multiply the 5% by the two years (presuming that it is 5% annual percentage rate (APR).  So, You will multiply the 110 by 10% (or .1) to get $11 dollars of simple interest.
