What is the area of the shaded sector?

What is the area of the shaded sector?

Answer: The area of the shaded sector of the circle is A = (θ / 2) × r2 where θ is in radians or (θ / 360) × πr2 where θ is in degrees. Let’s see how we will use the concept of the sector of the triangle to find the area of the shaded sector of the circle.

How do you find the area of the shaded region of a rectangle?

Answer: The area of the shaded region is 798.86 square units. To find the area of the shaded region, we will find the area of the circle given inside the rectangle and deduct this from the area of the rectangle.

What do shaded regions show?

The area of the shaded region is the difference between the areas of the rectangle and the square. Each side of the square measures 2 units and so the area is 2 times 2 , that is 4 square units. Therefore, the area of the shaded region is 48−4=44 square units.

How do you find the perimeter of a shaded area?

The area of a figure on grid is found by counting the total number of unit squares it occupies….Solution

1. The shaded shape on the grid is a rectangle.
2. Perimeter of the shaded shape = 3 + 4 + 3 + 4 = 14 units.
3. Area of the shaded shape = length × width.

What did you do to identify the area of the 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.

What is arc in circle?
