Question

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

Answer 1

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
