A right triangle is inscribed in a circle as shown. What is the area of the shaded region?
A. 5.04 square centimeters

B. 41.60 square centimeters

C. 77.32 square centimeters

D. 416.44 square centimeters

77.38 (almost answer C)

Step-by-step explanation:

The area of the circle is πr² = 36π ≈ 113.097

The side length of the "other" right side of the triangle is √(12²-9²) = √63

The area of the triangle is (9√63)/2 ≈ 35.717

So the shaded area is the difference, ie.: 113.097-35.717 = 77.38

cut 138 centimeters off

step-by-step explanation:

250-112 = 138

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
