(x - a)^2 + (y - b)^2 = r^2 is a circle with centre at (a, b) and radius of r
The correct answer is (x - 2)^2 + (y + 10)^2 = 9 ie the first one
I think it would be (x+7)/7
Total Area = r² π + 2 r h π = 6² π + 2 * 6 * 14 π = 204 π in²
Green Area = 2 * 6 * 8 π = 96 π in²
204 π ---------------100 %
96 π ----------------- x %
---------------------------------
x = ( 96 * 100 ) / 204 = 47.0588 ≈ 47.1
Answer:
<span>About 47.1 % of the ottoman is green ( not including the bottom ).
