  7. Circumference

  8. FIND THE DIAMETER of a circle with a CIRCUMFERENCE OF 376.80 CM. WORKING: 376.80cm Circumference

  9. Find the radius of a circle if its circumference is ……... (a) 25.12 cm Answer: 4 cm (b) 37.68 m Answer: 6 m Round your answer to the nearest whole number!

  10. Draw Half a Circle

  11. Draw a Quarter Circle

  12. Perimeter Find the perimeter of this shape 8cm Length of diameter = 8cm Perimeter of shape = 12.6 + 8 = 20.6cm(1dp)

  13. Perimeter Find the perimeter of this shape 3cm Length of radii = 3cm + 3cm = 6cm Perimeter of shape= 4.7 + 6 =10.7cm(1dp)

  14. Perimeter Find the perimeter of this shape 3cm 10cm Length of straight sides = 3 + 3 +10 =16cm Perimeter of shape = 15.7 + 16 = 31.7cm(1dp)
