(pi * radius squared) * ( sector angle / 360 )
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
Width, or diameter as it is more commonly known = 2*radius.
To find the area of the shaded part in a rectangle, you first find the total area of the rectangle by multiplying its length by its width. Then, you subtract the area of the non-shaded part from the total area to get the area of the shaded part. The formula would be: Area of shaded part = Total area of rectangle - Area of non-shaded part
You will need to divide the shaded area into smaller parts, such as triangles or rectangles, or find the length of sides of these polygons.
(pi * radius squared) * ( sector angle / 360 )
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.
Width, or diameter as it is more commonly known = 2*radius.
Sure thing, darling! To find the area of the shaded region in a circle with a central angle of 40 degrees and a radius of 9 cm, you first calculate the area of the entire circle using the formula A = πr^2. Then, you find the fraction of the circle that the shaded region represents, which is 40/360. Multiply this fraction by the total area of the circle to get the area of the shaded region. Easy peasy lemon squeezy!
Well, honey, the area of a shaded region is simply the difference between the total area and the area of the unshaded parts. Just calculate the area of the entire shape and subtract the areas of any parts that aren't shaded. It's basic math, darling, nothing to lose sleep over.
Typically, when a mathematical problem wants you to find the value of a shaded area, it wants you to calculate the area. If the shaded area is a circle, the area can be found by multiplying pi by the square of the radius. If the shape is a triangle, the area is base times height, divided by 2. If the shape is a square or rectangle, the area is length times width.

You will need to divide the shaded area into smaller parts, such as triangles or rectangles, or find the length of sides of these polygons.
(Length of side of square)^2 - Pi * radius^2
If you know the circumference then divide that by (2 x pi) and you will get the radius. The width is unnecessary information.
