168/4 to get the bike and the accessories to get 42
42x3=126
Answer:
15.7 cm
Step-by-step explanation:
Circle x's circumference is 15 * pi = 47.1 cm
Circle y's is 20 * pi = 62.8
The difference is 62.8 - 47.1 = 15.7
(x - h)^2 + (y - k)^2 = r^2
x^2 + (y + 6)^2 = 100
we can rewrite this as
(x-0)^2 + (y - -6)^2 = 10^2
the center is (0,-6) and the radius is 10
