Write a function called tankVolume that computes the volume of water in the tank. The function

should take exactly five input arguments in this order: $,,,,$ and $.$ It should return exactly one

return value, the volume of water in the tank. Your function should validate the input. More specifically,

check that all input values are greater than zero and that $<=(+).$ If any of the inputs are invalid,

the function should return a value of $-1.$ Test your function by the using the testTankVolume test stub.

Problem $1$ Pseudo Code

begin function

$\%$ return variable: vol

$\%$ Check for negative input values

if ra is negative

vol $=-1$

return

end

if ha is negative $...$

if rb is negative $...$

if hb is negative $...$

if h is negative $...$

$\%$ If input values are non$-$negative, compute the volume

if h $<$ ha

vol $=...\%$ use the first equation $($the one for a cylinder$)$

else if h is greater than ha and less than or equal to ha$+$hb

compute rw

vol $=...\%$ use the second equation $($the one for cylinder $+$ frustrum$)$

else

$\%$ in this case the value of h is invalid

vol $=-1$

end

end of function
