ANSWER
8 units.
EXPLANATION
The first point, A is located at (-9,2) on the coordinate plane.
The second point, B is also located at (-9,10) on the coordinate plane.
You should be smart and observe that the x-coordinates of both points are the same. This means that, the two points lies on a vertical line.
Hence it will be faster to use the absolute value method rather than the distance formula.
According to this method, you only have to find the absolute value of the difference in the y-values.

The surface area of the figure given is of: 61.3 yd².
<h3>What is the combined surface area of a figure?</h3>The combined surface area of a figure is the area of each figure.
This figure is composed by:
- A circle of radius 3 yd.
- A triangle with base 6 yd and one leg 11.4 yd.
The area of the circle is given as follows:
For the triangle, we need to find it's height, which is the <u>leg of a right triangle, in which one of the sides is 3 and the hypotenuse is 11.4</u>, hence:
h² + 3² = 11.4²
h = 11 yd.
Hence the area of the triangle is:
A = 0.5 x 6 x 11 = 33 yd²
The surface area of the figure is:
9pi + 33 yd² = 61.3 yd².
