Step-by-step explanation:

r≈3.5m

C Circumference

22

m

Using the formula

C=2πr

Solving forr

r=C

2π=22

2·π≈3.50141m

Approximately

3.5

m

Explanation:

The circumference of a circle C is equal to:

C

=

2

⋅

π

⋅

r

That's because the diameter of a circle fits

π

times in the circumference. So if you solve

r

r

=

C

2

⋅

π

=
