A circle represents a female. A square represents a male. A horizontal line connecting a male and female represents a marriage. A half-shaded circle or square indicates that a person is a carrier of the trait. A completely shaded circle or square indicates that a person expresses the trait.
How did you find the area of each shaded region?
Usually, we would subtract the area of a smaller inner shape from the area of a larger outer shape in order to find the area of the shaded region.
Is the shaded trait dominant or recessive?
For example, having a widow’s peak hairline is dominant. If an individual has that trait, their symbol on the pedigree will be shaded in. If they have no widow’s peak, their symbol will not be shaded in because having no widow’s peak is recessive.
What is the area of the shaded region of the rectangle?
The area of the shaded region is the difference between the areas of the rectangle and the square. The dimensions of the rectangle are 6 by 8 and so the area is 6 times 8 , that is 48 square units. Each side of the square measures 2 units and so the area is 2 times 2 , that is 4 square units.
What is the area of the shaded sector of the circle?
The area of the shaded sector is one-fourth of the area of the whole circle so: area of shaded region. The area of the shaded region is 9pi units^2.
How do you find the area of a shaded area?
Find the area of the shaded region by subtracting the area of the small shape from the area of the larger shape. The result is the area of only the shaded region, instead of the entire large shape. In this example, the area of the circle is subtracted from the area of the larger rectangle.
What is the area of the shaded portion within the square?
Area of shaded portion is 7.74 square units. Step-by-step explanation: We have to find the area of shaded portion. Since, the given figure consist of a square with side 6 cm and an quarter circle is made with radius 6 cm. Thus, Area of square = 6 × 6 = 36 square units. Area of quarter circle = square units.
What is the perimeter of the shaded area?
Answer: Perimeter of the shaded fighure is 14 π + 14cm. Footnote: Only those workings in the highlighted box are required to be written in your answer, the rest are just for you to understand how to do this question.
