Become familiar with methods used to calculate two-dimensional and three-dimensional objects.
Calculate Circumference, Area and Volume
TIP: Express all dimensions in terms of the same unit - for example, in terms of meter. A computed area will then be in terms of the square of the dimensional unit used - for example, square meter (m2) - and a computed volume will be in terms of the cube of the dimensional unit used - for example, cubic meter (m3).
- Circumference of circle: 3.1416 × diameter.
- Area of circle: 0.7854 × diameter × diameter.
- Area of rectangle: Length × width.
- Capacity of rectangular bin: Length × width × depth.
- Volume of cylinder: 0.7854 × diameter × diameter × height.
- Approximate capacity of container having sloping sides: vertical height × one-half the sum of top area and bottom area.
