Answer:
2
Step-by-step explanation:
Subtract the number with the term both sides ( which is 9)

Complete the square for the x terms and y terms.
( To complete the square divide the coefficient term by 2 and square it, then add that product to both sides.)


Take the square root of the right side to find the radius

The perimeter in 60 minutes is:
2 * pi * r
2 * pi * 8
50.26548246 inches
It moves from 12 to 2:
The perimeter will be:
(10/60) * (50.26548246)
Rewriting:
= (2/12) * (50.26548246)
= (1/6) * (50.26548246)
= 8.37758041
round to two-decimal places:
= 8.38 inches
Answer:
