Answer:
154cm2 (rounded to the nearest one)
Step-by-step explanation:
its just the radius (half the diameter) squared (times by itself) then times by pi π, simpified, πR2
Speed=Distance/Time
So Distance=Speed X Time
Distance=55T
Where 55 is the Car's speed and it is constant(won't change) and T is the time which is the changing variable.
you can plug time values to know the distance traveled!
