Mensuration

Lengths and areas of plane geometrical figures; lengths of arcs and chords of a circle; perimeters and areas of sectors and segments of circles; surface areas and volumes of simple solids and composite figures; the earth as a sphere — longitudes and latitudes.

• Calculate the perimeters and areas of triangles, quadrilaterals, circles and composite figures.
• Find the length of an arc, a chord, perimeters and areas of sectors and segments of circles.
• Calculate total surface areas and volumes of cuboids, cylinders, cones, pyramids, prisms, spheres and composite figures.
• Determine the distance between two points on the earth's surface.
