(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.
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.
To find the area of the circle pi*radius*squared and subtract the area of the figure inside
(pi * radius squared) * ( sector angle / 360 )
Find the area of the shaded region means find the area of the area that is shaded in or darkened.
The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
Width, or diameter as it is more commonly known = 2*radius.
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 we can't see the shaded area or if you don't tell us what it is, we'd just be guessing.
If you know the circumference then divide that by (2 x pi) and you will get the radius. The width is unnecessary information.
The probability is the ratio of the area of the shaded area to the area of the whole figure.
