You walk around a circle which has a diameter of 9 m, how far have you walked?

28.26 m

Step-by-step explanation:

Radius = 9/2 = 4.5m

Circumference = 2 * pi * r

= 2 * 3.14 * 4.5

= 28.26

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
