Answer:
7.99 m
Step-by-step explanation:
The formula for the circumference (C) of a circle in terms of its radius (r) is ...
C = 2πr
Putting in the given values, we can find r.
50.2 = 2·3.14·r
50.2/6.28 = r ≈ 7.99 . . . . . divide by the coefficient of r; round to 3 significant figures.
To 3 significant figures, the radius is 7.99 meters.
___
Rounded to the nearest tenth meter, it is 8.0 m.
