If the ratio of the triangular pyramids' surface areas is 4:9, what is F?
VladimirAG [237]

Answer:

The answer to your question is f = 10.35 in

Step-by-step explanation:

Data

Proportion = 4:9

height 1 = 4.6 in

height 2 = f

Process

1.- Write the proportion

                            \frac{4}{4.5} = \frac{9}{f}

2.- Solve for f

                            f(\frac{4}{4.6}) = f(\frac{9}{f})

                                   f(\frac{4}{4.6}) = 9

                                   4.6\frac{4f}{4.6} = 9(4.6)

                                           4f = 41.4

                           \frac{4f}{4} = \frac{41.4}{4}

                                           f = 10.35 in
