Error in variables being unset and unused

My issue stems from the subfunctions, I keep getting the error that the variable endarea is 'unset', and calcend is 'unused' and the same with every following function. This is the error message that shows up in the commmand line when run

>> geo(3,5)

calcend =

28.2743

Output argument "endarea" (and maybe others) not assigned

during call to "geo>calcend".

Error in geo (line 2)

enda = calcend(radius);

As you can see the first value is calculated and is correct, but then the error message. From here I have no clue what is happening or how to get the code running. the correct values output should be

End area = 28.27

Perimeter = 18.85

Side area = 94.25

Total area = 150.80

Volume = 141.37

function geo(radius, height)
enda = calcend(radius);
per  = perimeter(radius);
sida = areaofside(radius, height);
tota = totalarea(radius, height);
vol  = volume(radius, height);
printdata(enda, per, sida, tota, vol)
end
 
function endarea = calcend(rad)
calcend = pi*rad^2
end

function perimeterofbase = perimeter(radi)
perimeter = 2*pi*radi;
end

function sidarea = areaofside(radiu,h)
areaofside = 2*pi*radiu*h;
end

function areatotal = totalarea(radiuss,hi)
totalarea = 2*pi*radiuss^2 + 2*pi*radiuss*hi;
end

function volum = volume(radiusss, hig)
volume = pi*radiusss^2*hig;
end

function printdata(enda1,per1,sida1,tota1,vol1)
fprintf('end area        %6.2f\n', enda1);
fprintf('perimeter       %6.2f\n', per1);
fprintf('side area       %6.2f\n', sida1);
fprintf('total area      %6.2f\n', tota1);
fprintf('volume          %6.2f\n', vol1);
end

[Steven Lord]

function endarea = calcend(rad)
calcend = pi*rad^2
end

Your function is declared to return the contents of the variable named endarea in its workspace to its caller as the first (and only) output. Do you ever define a variable named endarea in the workspace of this function? If not, what should this function actually return to its caller?

Since the answers to those questions are "No" and "I don't know" respectively, MATLAB tells you "This function doesn't know what to return to its caller" only it words it slightly differently.

The solution is to define the variable named endarea inside this function. This solution also applies to the rest of your functions that declare that they return something to their caller, though with different names (perimeterofbase, sidarea, areatotal, and volum.)
