# Functions combining functions (solution)

Exercise

Write two functions:

- One called
`get_mass_from_length()`

that takes`length`

(in m),`a`

and`b`

as arguments, has the following default arguments`a = 39.9`

and`b = 2.6`

, uses the following code to estimate the mass (in kg)`mass <- a * length ^ b`

, and returns it. (This function is the answer to the Default Arguments exercise, so feel free to copy over your answer if you’ve done that exercise). - One called
`convert_kg_to_pounds`

that converts kilograms into pounds (`pounds = 2.205 * kg`

)

Use these two functions (each function should be called separately) to estimate the weight, in pounds, of a 12 m long Stegosaurus with

`a = 10.95`

and`b = 2.64`

(The estimated`a`

and`b`

values for*Stegosauria*from Seebacher 2001).Use these two functions (each function should be called separately) to estimate the weight, in pounds, of a 4 m long dinosaur using the default parameters.
