Use the non$-$fruitful function drawRect as a model. Write another non$-$fruitful function that draws a filled circle. The function is defined as

def drawFilledCircle$($t$,$ rad$)$:

$"""$ Draws a filled circle of radius rad using turtle t $"""$

and called with a statement like

drawFilledCircle$($axel$,$ radius$)$

The contents of the function are to begin filling, draw a circle, end filling.

Make sure you call your function in two different places in the program, using a different actual parameter each time.
