Formula
Area of a Rectangle
| F | Multiply the length by the width. | A=L×W | |
| Area of a Triangle | F | Multiply the base by the perpendicular height and divide by two. | A=12bh |
| Area of a Parallelogram | F | Multiply the base by the height. | A=b×h |
| Area of a Trapezium | F | Add together the parallel sides and multiply by the height. Divide your answer by two. | A=12(a+b)h |
| Area of a Circle | F | Square the radius and multiply by pi. | A=πr2 |
| Circumference of a Circle | F | Double the radius and multiply by pi or multiply the diameter by pi. | C=2πr or C=πd |
| Volume of a Cuboid | F | Multiply the length by the width by the height. | V=lwh |
| Volume of a Prism | F | Multiply the cross sectional area of the prism by its length. | n/a |
| Volume of a Sphere | H | Cube the radius and multiply by pi. Multiply your answer by four then divide by three. | V=43πr3 |
| Surface Area of a Sphere | H | Square the radius and multiply by pi. Multiply your answer by four. | A=4πr2 |
| Volume of a Cone | H | Square the base radius of the cone and multiply by pi. Multiply your answer by the perpendicular height. Divide your answer by three. | V=13πr2h |
| Curved Surface Area of a Cone | H | Multiply the base radius of the cone by pi. Multiply your answer by the length of the side of the cone. | A=πrl |
