Rounding to the nearest tenth does not make sense as the other numbers only have precision to the nearest whole number. Had they been reported as R = 6.0 m and h = 17.0 m, MAYBE asking to the nearest tenth would be reasonable. To be very precise, asking to the nearest tenth means the results have four significant digits and the dimensions and π should have been reported as R = 6.000 m, h = 17.00 m and π = 3.142
