4. Formula Which colour has the larger area? Area of a circle is A A = π r² π = 3.14 r is radius The red areas can be seen as four half circles which can make two circles
5. Formula Which colour has the larger area? Area of a circle is π r² π = 3.14 r is radius r The red areas can be seen as four half circles which can make two circles
6. Formula Which colour has the larger area? Area of a circle is π r² π = 3.14 r is radius r 3.14 x (r x r) or the radius multiplied by the radius then multiply by 3.14
7. Formula Which colour has the larger area? Area of a circle is π r² π = 3.14 r is radius r 3.14 x (r x r) or the radius multiplied by the radius then multiply by 3.14 1
8. Formula Which colour has the larger area? Area of a circle is π r² π = 3.14 r is radius r 3.14 x ( 3 x 3 ) or 3 multiplied by 3 = 9 then multiply by 3.14 =
9. Formula Which colour has the larger area? Area of a circle is π r² π = 3.14 r is radius r 3.14 x ( 3 x 3 ) or 3 multiplied by 3 = 9 then multiply by 3.14 = 28.26
10. Formula Which colour has the larger area? Area of a circle is π r² π = 3.14 r is radius r 3.14 x (r x r) or the radius multiplied by the radius then multiply by 3.14
11. Formula Which colour has the larger area? Area of a circle is π r² π = 3.14 r is radius r 3.14 x ( 2 x 2 ) or 2 multiplied by 2 then multiply by 3.14 =
12. Formula Which colour has the larger area? Area of a circle is π r² π = 3.14 r is radius r 3.14 x ( 2 x 2 ) or 2 multiplied by 2 then multiply by 3.14 =12.56
13. Formula Area (square) = 9 x 9 = 81; Area (red) = 28.26 + 12.56 = 40.82; Area (yellow) = 81 - 40.82 = 40.18. Thus, Area (red) > Area (yellow).

15. Formula A right angled triangle has sides of 3 cm and 4 cm find the length of the Hypotenuse (the longest side)
20. Formula 3 cm 4 cm C A B A² + B² = C² (A x A) + (B x B) = (C x C)
21. Formula 3 cm 4 cm C A B A² + B² = C² (A x A) + (B x B) = (C x C) A multiplied by A B multiplied by B C multiplied by C Added to Equals
22. Formula 3 cm 4 cm C A B A² + B² = C² (A x A) + (B x B) = (C x C) A multiplied by A B multiplied by B C multiplied by C Added to Equals (3 x 3) + (4 x 4) = (C x C)
23. Formula 3 cm 4 cm C A B A² + B² = C² (A x A) + (B x B) = (C x C) A multiplied by A B multiplied by B C multiplied by C Added to Equals 9 + 16 = (C x C)
24. Formula 3 cm 4 cm C A B 9 + 16 = (C x C) 25 = C x C
