A triangle is placed in a semicircle with a radius of 7cm, as shown below. Find the area of the shaded region. Use the value 3.14 for π, and do not round your answer. Be sure to include the correct unit in your answer. 7cm

The answer is 27.93π2

Area for a triangle: 1/2 x length x width

Area for a semi circle: 1/2 x radius^2 x TT

Radius: 7yd

Diameter: 14yd

Triangle:

7 x 14 x 1/2 = 49yd^2

Semi Circle:

7^2 x TT x 1/2 = 76.93yd^2

Subtract the triangle's area from the semi circle's to get the remainder, or the shaded region's area:

76.93 - 49 = 27.93yd^2
