Equation: 
Step-by-step explanation:
Let parking spaces in each row
In 
level there are 
so total number of parking spaces in 1 level
There are 
level so total number of parking spaces
X^2 + y^2 - 2x + 8y - 47 = 0
x^2 + y^2 - 2x + 8y = 47
(x^2 - 2x) + (y^2 + 8y) = 47
(x^2 - 2(1)x) + (y^2 + 2(4)y) = 47
(x^2 - 2(1)x + 1^2) + (y^2 + 2(4)y + 4^2) = 47 + 1^2 + 4^2
(x - 1)^2 + (y + 4)^2 = 64 = 8^2
r=8
The area (A) of the whole circle is calculated through the formula, A = πd² / 4. Substituting the given diameter, A = π(10 in)² / 4 = 25π in². The area of the top of each piece is 1/6 of the this area. Thus, the answer is approximately 4.17 in².
