Determine the area of the entire shape?
A trapezoid is shown in the figure below.
On its upper base there is a semicircle.
What is the area of the entire shape?
Two circles share a center point, marked O.
What is the area of the shaded part of the orange circle?
Look at the circle in the figure.
Its center is O.
Inside the circle there is a square.
What is the area of the white parts combined?
From the point O on the circle we take the radius to the point D on the circle. Given the lengths of the sides in cm:
DC=8 AE=3 OK=3 EK=6
EK is perpendicular to DC
Calculate the area between the circle and the trapezoid (the empty area).
Observe the rectangle in the figure below.
A semicircle has been added to each side of the rectangle.
Determine the area of the entire shape?
The area of the entire shape equals the area of the rectangle plus the area of each of the semicircles.
Let's begin by labelling each semicircle with a number:
Therefore, we can determine that:
The area of the entire shape equals the area of the rectangle plus 2A1+2A3
Let's proceed to calculate the area of semicircle A1:
Let's now calculate the area of semicircle A3:
Therefore the area of the rectangle equals:
Finally we can calculate the total area of the shape:
cm².
A trapezoid is shown in the figure below.
On its upper base there is a semicircle.
What is the area of the entire shape?
cm².
Two circles share a center point, marked O.
What is the area of the shaded part of the orange circle?

Look at the circle in the figure.
Its center is O.
Inside the circle there is a square.
What is the area of the white parts combined?
23.085 cm²
From the point O on the circle we take the radius to the point D on the circle. Given the lengths of the sides in cm:
DC=8 AE=3 OK=3 EK=6
EK is perpendicular to DC
Calculate the area between the circle and the trapezoid (the empty area).

The trapezoid ABCD is drawn inside a circle.
The radius can be drawn from point O to point C.
DC = 12 cm
OK = 3 cm
NB = 4 cm
NK = 5 cm
Calculate the white area between the trapezoid and the circle's edge.
The drawing shows an equilateral triangle
The length of each of its sides 7 cm
a semicircle is placed on each side of each side
What is the area of the entire shape? Replace \( \pi=3.14 \)
