Question

Sort the circles into columns that show their correct measurement. Use 3.14 for pi

8cm
10cm
5cm
8ft
4cm
4cm

Answer 1

Circles with a radius of:
- 4cm, circumference = 2 x 3.14 x 4 = 25.12 cm
- 4cm, circumference = 2 x 3.14 x 4 = 25.12 cm
- 5cm, circumference = 2 x 3.14 x 5 = 31.4 cm
- 8cm, circumference = 2 x 3.14 x 8 = 50.24 cm
- 10cm, circumference = 2 x 3.14 x 10 = 62.8 cm
- 8ft = 243.2 cm

Therefore, the circles sorted by their correct measurement are:
- 8ft
- 4cm
- 4cm
- 5cm
- 8cm
- 10cm
