Answer:

22 meters

Step-by-step explanation:

The circumference of a circle is expressed as;

C = 2 pi r

r is the radius of the circle

Given

radius r = 3 1/2meters

pi = 22/7

Substitute into the formula

Circumference of the circle = 2 * 22/7 * 3 1/2

Circumference of the circle = 2 * 22/7 * 7/2

Circumference of the circle = 44*7/14

Circumference of the circle = 44/2

Circumference of the circle = 22meters

Hence the Circumference of the circle is 22 meters
