Honestly I believe the snail would travel 2.5 more centimeters in 6 minutes. so technically the snail traveled 12.5 cm in 6 minutes.
The second bicycle would weigh 1.32142857143 pounds or rounded to 1.32.
You would find this by multiply 18.5 by 1/14
Since the standard form of the circle is:
(x-h)^2+(y-k)^2=r^2, and (h,k)=(0,0) and r=10 so we have:
x^2+y^2=100 Looking at the points you have:
(√10, 0) does not work as (√10)^2+0^2=10+0=10
(0, 2√5) does not work as 0^2+(2√5)^2=0+20=20
(5√2, 5√2) works as (5√2)^2+(5√2)^2=50+50=100
