**helper**, Wednesday, January 19, 2011 at 8:40pmr = radius

3r = height (h)

SA = 2(pi)(r)(h) + 2(pi)(r^2)

SA = 2(pi)(r)(3r) + 2(pi)(r^2)

SA = 6(pi)(r^2) + 2(pi)(r^2)

SA = 8(pi)r^2

402 = 8(pi)r^2

402 = 8(3.14)r^2

402 = 25.12r^2

16.00318 = r^2

rounding 16.00318 = 16

16 = r^2

r = 4

height = 3r = 3(4) = 12
