Add all the number the points are on and you get your answer
Given:
AD is diameter of the circle, AB is the tangent, and measure of arc ADC is 228 degrees.
To find:
The and .
Solution:
AD is diameter of the circle. So, the measure of arc AD is 180 degrees.
The measure inscribed angle is half of the corresponding subtended arc.
AB is the tangent. So, because radius is perpendicular on the tangent and the point of tangency.
Therefore, and .

Step-by-step explanation:
Your goal is to find the area of the island of grass and multiply that area by the cost per square yard.
Area = radius * radius * pi
You are told that the <em>diameter = 15 yards</em>. We also know that the radius that we need is half of the diameter. <em><u>Radius = 7.5 yards</u></em>.
This means that the <em>Area = 7.5 * 7.5 * 3.14 = 176.625 square yards</em>
Then we multiply by the cost per square yard:
176.625 * 6.50 = 1148.06 is your answer
