Answer: (x)^2 + (y)^2 = 90,000
Step-by-step explanation: we know that
The equation of the circle (the roof of the Colosseum) in standard form is equal to (x-h)^2 + (y-k)^2 =r^2
where
(h,k) is the center and r is the radius
we have
(h,k)=(0,0) ----> is the origin
----> the radius is half the diameter
substitute
Answer:
56 ft
Step-by-step explanation:
Answer
18 hours
if 10 people spend 15 hours
one person spend 15/10=1.5
so 1.5 × 12=18hours
Answer: C
since the line isn't straight, the slope/function is decreasing but not at a constant rate
when x is r + 2 :
