-13 = x+1
what is the answer to this question ?

x = -14

Step-by-step explanation:

x + 1 - 1 = -13 - 1

x = -14

314.16 m

Step-by-step explanation:

The distance across the track is 100 metres. This means that the diameter is 100 m.

The track is circular, so, we need the circumference.

The circumference of a circle is given as:

C = πD

where D = diameter

Therefore, the circumference of the track is:

C = π * 100 = 314.16 m

She walked a distance of 314.16 m
