2:15+2:31=4:46
4:46+1:16=5:62=6:02
6:02+2:56 =8:56pm or 20:56
Answer: (x+7)^2 + (y-4)^2 = 121 or (x+7)^2 + (y-4)^2 = 11^2
Step-by-step explanation:
Equation of the circle is:
, which is the center
and the radius 
-Place the center (-7,4) and radius 11 onto that equation:
(if simplified radius needed)
or

Answer:
The wheel have made
revolutions.
Step-by-step explanation:
The total distance traveled during the race is
D = 4510km [(1000m)/(1km)] = 
The radius (r1) of the smaller bicycle wheel is
r1 = 
Than the larger wheel has a radius
r2 = 0.329 m + 0.012 m = 0.341 m
Over the same distance this wheel would make N2 revolutions
N2 =
