The light's coverage area is given mathematically as i.e. Area=
Given that a lighthouse casts a revolving beam of light as far as they peir and asked the area is covered.
The revolving beam of light covers the whole space i.e entirely 360°
I.e. it forms a circle-like region
Area of circle = 
{ where r is the radius of circle}
Let's assume the distance traveled by light as "d"
as it forms a circular region, it forms a circle of radius "d"
Mathematical connection i.e. area of the region
⇒area of circular region= {where d is the radius of region}

21,
if you would like me to explain how to do it, I can in the comments.
The inequality is 7x + 21 
Step-by-step explanation:
<u>DATA:</u>
Let the number be x
Number times 7 = 7*x
Sum of a number times 7 and 21 = 7x + 21
Is at least 29
<u>INEQUALITY:</u>
7x + 21
<u>SOLVE:</u>
7x 
7x 
x 
Therefore, the inequality is 7x + 21

These two angles are congruent so
12x + 3 = 11x + 9
X = 6
Plug in 6 so 12(6)+3=75
Both angles measure 75 degrees
