<PRE><B>Question 752527</B>
surface area equals two times the area of the base plus the lateral area.


area of the base = pi * r^2


lateral area = 2 * pi * r * h


total surface area = 2 * pi * r^2 + 2 * pi * r * h


desired measurements are radius of 5.1cm and height of 15.1 cm.


surface area with those measurements = 2 * pi * (5.1)^2 + 2 * pi * 5.1 * 15.1


this is equal to 647.2937503 square cm.


actual measurements are radius of 5 cm and height of 15 cm.


surface area with those measurements = 2 * pi * 5^2 + 2 * pi * 5 * 15


this is equal to 628.3185307


the difference from the desired amount is equal to 18.97521963 square cm.


the % difference from the desired amount is equal to 3.02%
