Answer 1

Exact distance = 175π m

Approximate distance = 549.5 m

Explanation:

In a full revolution he travels the distance equal to the circumference of the circle.

C = πd

Exact distance:

C = π × 175 m

C = 175π m

Exact distance = 175π m

Approximate distance:

175 × 3.14 m = 549.5 m

Approximate distance = 549.5 m
