Answer:
31.42 cm (rounded up to two decimal places)
Step-by-step explanation:
We first find the circumference of the semi-circle segment:
The circumference will be given by; 
× π × D (where D is the diameter)
The diameter is 6 cm so circumference is;
× π × 6 cm = 9.42 cm (rounded up to two decimal places)
The perimeter of the figure therefore is;
8cm + 6 cm + 8 cm + 9.42 cm = 31.42 cm

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.

First you solve for X then substitute the number you got for X and then solve for Y.
Your answer is: y=5
Here are the steps:
<span>4=2/9(4y-2)
=2/9(4y-2)=4
=9*</span>2/9(4y-2)=4*9
=2(4y-2)=36
=2(4y-2)/2=36/2
=4y-2=18
=4y-2+2=18+2
=4y=20
=4y/4=20/4
=y=5
