What is the area of the shaded region?

(25π – 48) cm2
(25π – 30) cm2
(25π – 24) cm2
(25π – 12) cm2

1) find the are of the circle: πr²

2) find the area of each triangle: (base x altitude)/2

3) subtract the triangles from the circle are

1) area of circle:π.5² = 25 π

2) Area of the triangle = (6 x 4)/2 =12 cm². We also notice that both triangles are congruent SSS (6,5 & 5), so the total surface of the 2 triangles = 24 cm²

3) (25π - 24) cm² is the answer

72 is the mode because it shows up the most number of times
