How do you find out the area of a shaded region?
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 region as shown in the figure?
Q3. In the given figure, find the area of the shaded region, if ABCD is a square of side 14 cm and APD and BPC are semicircles. Q4. In the given figure, ABCD is a square of side 7 cm, DPBA and DQBC are quadrants of circles each of the radius 7 cm.
What is the area of the shaded triangle answer?
Area of the shaded triangle ABC = (1/2)(|AP||BC|) = (10)(|AP|). Triangle EBC is similar to triangle APC. Therefore, AP/PC = EB/BC = 4/20 = (1/5). Also triangle DCB is similar to triangle APB.
What is the meaning of shaded area?
A shaded area on something such as a map is one that is coloured darker than the surrounding areas, so that it can be distinguished from them. adj. -shaded. -shaded combines with nouns to form adjectives which indicate that sunlight is prevented from reaching a certain place by the thing mentioned.
What is the area of the triangle?
The area of each triangle is one-half the area of the rectangle. So, the area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.
How do you calculate the area of the shaded region?
Calculate the area of the shaded region in the right triangle below. Solution. Area of shaded region = area of outer shape – area of the unshaded inner shape. Area of a triangle = ½ bh. Area of outer shape = (½ x 15 x 10) cm 2. = 75 cm 2. Area of unshaded inner shape = (½ x 12 x 5) cm 2. = 30 cm 2.
How do you find the shaded area of a hexagon?
Area of the shaded region = area of the square – area of the four unshaded small squares. The side length of the four unshaded small squares is 4 cm each. Calculate the shaded area of the square below if the side length of the hexagon is 6 cm. Area of the shaded region = (225 – 93.53) cm 2.
How do you find the shaded region of a polygon?
Such questions always have a minimum of two shapes, for which you need to find the area and find the shaded region by subtracting the smaller area from the bigger area. Or we can say that, to find the area of the shaded region, you have to subtract the area of the unshaded region from the total area of the entire polygon.
What is the portion of a circle that I drew called?
The portion that you drew is referred to as an arc. An arc may be a portion of a full circle, a full circle, or more than a full circle, represented by more than one full rotation. The length of the arc around an entire circle is called the circumference of that circle.
