Work through them in order.
- Not startedUnits, heights and composite areaNextConvert squared and cubed units, then use perpendicular heights and non-overlapping regions to calculate area.
- Not startedCircles and composite boundariesNextUse the radius for circle area and trace every part of a composite boundary.
- Not startedCuboids and liquid volumeNextUse complete layers to derive cuboid volume and measure liquid in a rectangular tank.
- Not startedPrisms, cylinders and exposed surfacesNextSeparate cross-sectional area, perpendicular length, volume and the surfaces actually exposed.
- Not startedPyramids, cones and spheresNextDistinguish perpendicular height, slant height and radius when using volume and surface-area formulae.
- Not startedDegree sectors and arc lengthsNextUse the sector’s share of a full turn and distinguish an arc from the complete sector perimeter.
