Answer:
Here c represents the total number of children in choir.
As per the statement:
Total number of boys in choir = 12
It is also given that: Three sevenths of a children's choir are boys.
⇒ Total number of boys = 
or

By cross multiply we have;
84 = 3c
Divide both sides by 3 we have;
c = 28
Therefore, the total number of children in choir is 28 children

- First find the area of the whole circle
The equation is :
πr^2
Substitute the radius in:
π(5)^2
Solve:
Area of full circle = 25π
(Note : leave this answer in terms of 'pi' so it is easier to handle
Next, find the area of the sector
The equation for this is:
(angle/360) x πr^2
Substitute the values in:
(80/360) x π(5)^2
Solve :
Area of sector = (50/9)π
Now, find the area of the triangle:
1/2 absinC
Substitute the values in:
1/2(5)(5) x sin(80) = 12.31009691
Subtract this answer from the area of the sector
Answer = 5.14319607
Subtract this from the area of the whole circle
Answer = 73.39662073
To the nearest tenth, that would be 73.4 cm^2

<h3>WHAT IS DILATION ?</h3>
A dilatation is a transformation that increases an image's size without altering its form or ratios.
It's similar to how when Ant-Man grows or shrinks, every portion of his body shrinks or grows by the same amount, leaving him with the same appearance. In terms of human physiology, the word "dilation" refers to relaxation, opening, or widening. This is typically utilised in buildings where materials can pass through. Due to the fact that dilation is an autonomic process, it cannot be actively managed. It is a technique for regulating or directing how things move through the body, including solids, liquids, and both.
Simply said, smooth muscle. One of the three types of muscles in the body, smooth muscle is frequently seen in internal organs like the stomach, bronchi, and bladder. Blood vessels and muscle sphincters are two other structures that contain smooth muscle. These organs and structures can dilate as a result of smooth muscle relaxation.
