posted by on .

what is the ratio of the surface areas for a pair of similar cylinders when the ratio of the heights is 1:3?
i don't understand this at all!!

  • MATH 157 - ,

    the surface area of similar figures varies directly as the square of their corresponding sides

    so surface area(1)/surface area(2) = (1^2)/(3^2) = 1/9

    so the surface area of the larger cylinder is 9 times that of the smaller.
