Answer:
A
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Given (h, k) = (0, - 7) and r = 11, then
(x - 0)² + (y - (- 7))² = 11², that is
x² + (y + 7)² = 121 → A
Answer:
Machine B
Step-by-step explanation:
Since, Machine A covers
square feet in
hours,
Rate at which the Machine A is covering = 
= 
= 2.5 square feet per hour
Machine B covers
square feet in
hours,
Rate at which the Machine B is covering = 
= 
= 
= 3.33 square feet per hour
Therefore, Rate of Machine B is greater.
