Answer 1

The circumference of the circle is found as ; c=2πr where π= 3.14 and r= radius

If diameter is given, then we can simply find the circumference as πd because d= 2r

1. d=5.9 ft

circumference =
`3.14*5.9=18.526` ft

2. d=3.2 ft

c=
`3.14*3.2=10.048` ft

3. d=6.1 cm

c=
`3.14*6.1=19.154` cm

4. r=3.7 m

c=
`2*3.14*3.7=23.236` m

5. r= 6.2

c=
`2*3.14*6.2=38.936`

6. r= 5.1 ft

c =
`2*3.14*5.1=32.028` ft
