area of the white square + yellow square = (1.4142*3)^2=18 sq cm
area of the yellow square is =(0.7071*1.4142*3)^2=9sq cm
thus area of four triangles is 9 sq cm
whole area = 9*pi
therefore yellow area =2.14159*9=19.27431 sq cm
its 3.14*3*3 - 4* (1.5*1.5)
= 19.26 cm2
The diagonal of bigger square is 6cm(diameter)
Therefore it's side is 3root2 cm.
Now as the diagonal of smaller square is equal to the side of larger square
There fore the side of smaller square is 3cm
Yellow part =(area of circle-area of larger square)+ area of smaller square
9 pie -18+9
= 9 pie-9
A circle has a radius of 12 units and its center is at one vertex of a square. The square has a side of 12 units. Find the area of the shaded region?
If you knew that the radius of the big circle and the big arcs is 5 cm, what is the area of the yellow region?
The radius of the given circle is 7 cm, then what is the area of the shaded portion?
The 2 diagonals of this rectangle divide it into 4 triangles.
If the area of the shaded region is 42, then what is the area of the rectangle?
