Answer:
20.8 inches squared
Step-by-step explanation:
Area of spinner:
45.1 is the area of sectors where the token doesn't move, which 5 sectors doesn't move the token (don't forget that the bonus points doesn't move token). Then
45.1/5=9.02
9.02*12=108.24
K=1/2(r^2)sin150
108.24=1/2(r^2)sin150
216.48=(r^2)1/2
432.96=r^2
r=20.8

Answer: 2.5 times
Step-by-step explanation:
Given : The length of Chase’s bike ride=
The length of Maddie’s bike ride=
In improper fraction : Length of Chase’s bike ride=

Similarly , Length of Maddie’s bike ride= 
The number of times the length of Chase’s bike ride was Maddie’s bike ride= 

Hence, the length of Chase’s bike ride was 2.5 times Maddie’s bike ride.
