Step-by-step explanation:
Answer:
3/4
Step-by-step explanation:
let x = females
3x = males
3x + x = 4x
fraction of males = 3x / 4x = 3/4
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
-5 to 10 would fit all the numbers
