Find Area of the circle:
------------------------------------------------------------------------------
Area of a circle = πr²
Area of the largest possible circle = π x(12 ÷ 2)²
Area of the largest possible circle = 113.10 ft²

Find Area of the square board:
------------------------------------------------------------------------------
Area of a square board = Length x Length
Area of the square board = 12 x 12
Area of the square board = 144 ft²
------------------------------------------------------------------------------
Find area of the remaining board:
------------------------------------------------------------------------------
Area of the remaining board = 144 - 113.10
Area of the remaining board = 30.90 ft²
------------------------------------------------------------------------------
Answer: The area of the remaining board is 30.90 ft².

Step-by-step explanation:
we will simplify it
Answer:
Every polygon is either convex or concave. The difference between convex and concave polygons lies in the measures of their angles. For a polygon to be convex, all of its interior angles must be less than 180 degrees. Otherwise, the polygon is concave.
Answer:
P = 24.135 pounds per square inch
Step-by-step explanation:
The air pressure in the tire should be 
pounds per square inch. This pressure is in the form of a mixed fraction. It is required to convert this pressure into a decimal form. We can convert it as follows :
In decimal form, the value of pressure in the tire on the digital pressure gauge is 24.135 pounds per square inch.
