Pythagorean Theorem: A^2 + B^2 = C^2
We know A and C, let's find B by doing it backwards 

C^2 - A^2 = B^2 
4^2 - 7 (square root of 7 squared is just 7) = B^2 
16 - 7 = B^2 
9 = B^2

The largest possible circle is to be cut from a 12-foot square board. Calculate the approximate area, in square feet, of the rem

olchik [2.2K]

------------------------------------------------------------------------------
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.
