Answer: Mike's arm span is 7.165 cm longer than the George's one.
Step-by-step explanation:
We have that the association between height and arm span is modeled by the equation
y = 4.5 + 0.977*x
where y is height and x is arm span.
Mike is 172 cm tall, so his arm span is:
172cm = 4.5 + 0.977*x
x = (172 - 4.5)/0.977 = 171.443 cm
and George is 165 cm tall, so his arm span is:
x = (165 - 4.5)/0.977 = 164.278 cm
Then the difference between their arm span is:
171.443cm - 164.278cm = 7.165 cm
So Mike's arm span is 7.165 cm longer than the George's one.

Question
What is the diameter of 11.94 cm circumference
Answer:
Soln,
We know that diameter = * 2 radius
radius = 11.94/2= 5.97 half of diameter and when you multiply with 2 ,Then it comes 11.94cm
Now
Step-by-step explanation
Circumference = 2πr
11.94 = 2*22/7*r
11.94 = 6.28r
r= 11.94/6.28
therefore, r= 1.90 cm
Now
We know that diameter = * 2 radius
diameter = 1.90*2 = 3.80 cm
answer checking,
Circumference = 2πr
c= 2*22/7*1.90
therefore c = 11.94 cm
