Answer:

"Solve for the circumference."

1. r = 5 cm, C = 31.4 cm

2. d = 6 in, C = 18.84 in

3. r = 10 m, C = 62.8 cm

4. d = 12 cm, C = 37.68 cm

5. r = 2 in, C = 12.56 in

Solutions:

1.

Given:

  • r = 5 cm
  • π = 3.14

Formula:

  • C = 2πr

Solution:

  • C = 2πr
  • C = 2(3.14)(5 cm)
  • C = 2(15.7 cm)
  • C = 31.4 cm

2.

Given:

  • d = 6 in
  • π = 3.14

Formula:

  • C = πd

Solution:

  • C = πd
  • C = (3.14)(6 in)
  • C = 18.84 in

3.

Given:

  • r = 10 m
  • π = 3.14

Formula:

  • C = 2πr

Solution:

  • C = 2πr
  • C = 2(3.14)(10 m)
  • C = 2(31.4 cm)
  • C = 62.8 cm

4.

Given:

  • d = 12 cm
  • π = 3.14

Formula:

  • C = πd

Solution:

  • C = πd
  • C = (3.14)(12 cm)
  • C = 37.68 cm

5.

Given:

  • r = 2 in
  • π = 3.14

Formula:

  • C = 2πr

Solution:

  • C = 2πr
  • C = 2(3.14)(2 in)
  • C = 2(6.28 in)
  • C = 12.56 in
