<u>Given</u>:
A triangle is placed in a semicircle with a radius of 6 cm.
We need to determine the area of the shaded region.
<u>Area of the triangle:</u>
The area of the triangle can be determined using the formula,
Substituting b = 6 and h = 6, we get;
Thus, the area of the triangle is 18 cm²
<u>Area of the semicircle:</u>
The area of the semicircle can be determined using the formula,
Substituting π = 3.14 and r = 6, we get;
Thus, the area of the semicircle is 56.52 cm²
<u>Area of the shaded region:</u>
The area of the shaded region can be determined by subtracting the area of the triangle from the area of the semicircle.
Thus, we have;
Area = Area of semicircle - Area of triangle
Substituting the values, we get;
Thus, the area of the shaded region is 38.52 cm²
