Seven groups waited in line to see a concert. there were 9 people in each group. how many people were there in total?
9x7= 63
The height is given as 9 ft. this is also the radius of the circle.
The base of the triangle would be 2 times the radius = 18 feet.
The area of the triangle is 1/2 x 9 x 18 = 81 square feet.
The area of the semi circle is : 1/2 x PI x r^2 = 1/2 x 3.14 x 9^2 = 127.17
The area of the shaded region is the area of the triangle minus the area of the semi circle:
127.17 - 81 = 46.17 square feet.
