Question

Rosie is training for the next football match. she runs around a circular track with a radius of 60 metres. use π = 3.14 and c = πd how far has rosie run?

Answer 1

The answer is 376.8 m.

It is given:
radius: r = 60 m
π = 3.14
c = π * d
d - diameter.

It is known that diameter is twice of radius:
d = 2r

So, implement it in the formula:
c = π * d = π * 2r = 3.14 * 2 * 60 = 376.8 m
