Q2. The large wheel on Dmitrys wheelchair has a diameter of 57.2 cm. He pushes the wheel round 10 times. How far does he move? Q1. Find the circumference of this circle. ? = ? 8 = 25.13 ?? (2dp) Circumference = ?x Diameter
How can we find the perimeter of this shape? Circumference = ?x Diameter 10 cm ? = ? + ? ? = (? 10) 2 ? = 10 ? = 25.71 ?? (2dp)
What is the perimeter of this shape? ? = ? ? = 10 ? =1 5cm 4 10 + 2 5 17.9cm Answer to 1 dp.
What is the perimeter of this shape? ? = ? ? = 10 ? =1 2 10 + 10 10m 25.7m Answer to 1 dp.
What is the perimeter of this shape? ? = ? ? = 8 ? =1 8cm 2 8 + 8 20.6cm Answer to 1 dp.
What is the perimeter of this shape? ? = ? ? = 16 ? =1 4 16 + 2 8 28.6mm Answer to 1 dp.
What is the perimeter of this shape? ? = ? ? = 18 ? =1 2 18 + 18 9m 46.3m Answer to 1 dp.
What is the perimeter of this shape? ? = ? ? = 8 ? =3 4 8 + 2 4 26.8cm Answer to 1 dp.
Work out the perimeter SET A SET B Give your answer to 1 decimal place
Mark your work SET A 42.8 cm 14.3 cm 20.6 cm 15.4 cm SET B 18.0 cm 32.1 cm 20.6 cm 33.1 cm 27.4 cm Give your answer to 1 decimal place 21.4 cm 37.7 cm 33.1 cm
TRUE or FALSE? A B C D 18 cm If the circumference of a circle is 1 m, the diameter is 31.83 cm (to 2dp). If the circumference of a circle is 50 cm, the radius is 8.0 cm (to 1dp). 8 cm Circumference = 25.1 cm Radius = 5.7 cm E F G H 13,000 km 7 cm 20 cm 10 cm 6.5 cm Perimeter = 35 cm Perimeter = 51.4 cm Perimeter = 23.4 cm It is 40,000 km around the world.
