| Fluid Conversion | 1000mL = 1L 1cm3 = 1mL 1000cm3 = 1L |
| How do you find the difference in hours? | Both times must be in analogue eg. 9:30pm + 0900 = 2130 + 0900 |
| How do you find the perimeter and area for a circle? | Perimeter = π x Diameter Area = π x radius2 |
| What is diameter and radius? | Diameter = any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. Radius = the length of a line segment from its center to its perimeter. |
| How do you find the perimeter and area of a semicircle? | Perimeter = π x diameter ÷ 2 Area = π x radius2 ÷ 2 |
| How do you find the perimeter and area of a quarter of a circle? | Perimeter = π x (8 x 2) ÷ 4 + (8 x 2) Area = |
