Question 1154620
<br>
Technically, the question can't be answered, because we are not told that the segment of length 10 is a diameter....<br>
Assuming it is, the radius of the circle is 5, so the area of the whole circle is 25pi.<br>
The given angle is 72 degrees, so the central angle of the shaded region is 180-72 = 108 degrees.<br>
The area of the shaded region is then 108/360 of the area of the whole circle.<br>
Use a calculator and express the answer in the required form.<br>
