Using the approximation 3.14 for pi π​, what is the radius of a circle with circumference 50.2 m?
bearhunter [10]

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.
