Answer:
C =28.26m
Step-by-step explanation:
We are walking around a circle, which means we are finding the perimeter. The perimeter of a circle is called the circumference.
We find the circumference by
C = pi *d where d is the diameter
C = 3.14 * 9
C =28.26m
Answer:
28.26 m
Step-by-step explanation:
Radius = 9/2 = 4.5m
Circumference = 2 × pi × r
= 2 × 3.14 × 4.5
= 28.26
