[FIRST BRAINLIEST GIVEAWAY] To enter answer this question! The radius of the semicircle in the following composite figure is 8.5 millimeters. What is the area of the semicircle rounded to the nearest hundredth?

A-C:
226.87 mm2
907.46 mm2
113.43 mm2
453.73 mm2

C) 113.42

Step-by-step explanation:

Hope I helped! :)

Note: Brainliest appreciated

The area of the circle is calculated through the equation,

                               A = πr²

With this reasoning, the value of the area of the semicircle is equal to  

                                      A = πr²/2

Substituting the known variables,  

                                         A = π(8.5 mm)²/2

                                         A = 113.49 mm²

Therefore, the answer is approximately 113.43 mm², third choice.
