Hi everyone!

can anyone help me with those 2 maps questions

1_ A very large standing stone was erected by an early civilisation as a sentinal. Archaeologists measured the girth (circumference) of the stone at heights seprated by 1m. They found the girths to be 6.3m (at ground level), 5.4m, 4.6m, 4.4m, 4.8m, and 3.9m, and then the stone tapered to a point at a height of 6m. Assuming that the stone is made of basalt of density 2800kg/m^3 and is nearly square in cross-section, find an approximation for the mass of the stone.

2_ The circumference of the trunk of a stringybark is measured at ground height and at heights separated by 5m, with the following results: 8.4m, (ground), 8.3m, 8.2m, 7.4m, 6.3m, 54,m 4.8m, 3.6m, 3.4m, 3.2m, 2.7m, 2.1m, 1.4m, 1.2m, 0.9m, 0.6m, 0.4m, 0.2m, 0.1m, then tapering to the top at a height of 95m. Find an approximation for the volume of wood in the log from this tree.

If anyone can draw the diagrams plz do it.
thanks
