The value of x will be equal to 6 units.
<h3>What is trigonometry?</h3>Trigonometry is the branch of mathematics that set up a relationship between the sides and angle of the right-angle triangles.
Given that:-
Given that the radius of the circle is 9 which is SO= 9 and SG = 9.
Now the value of x will be calculated by using the Pythagorean theorem.
H² = P ² + B ²
OG² = 12² + 9 ²
OG = √225
OG = 15
Since, OG = OH + HG
HG = OG - OH
x = 15 - 9
x = 6 units
Therefore the value of x will be equal to 6 units.

Answer:
54.5
Step-by-step explanation:
divide it to one rectangle and two different triangles.
Rectangles area: (8+3)*4 = 44
triangle top: 4*3/2 = 6
triangle bottom: 3*3/2= 4.5
sum the all up: 44+6+4.5 = 54.5
don't know how to do it with π though if that's obligatory
