evaluate : integral {-r; -r+d} sqrt (r^2 - y^2) dy

The symbols r and d represent constants.

The symbol y is the variable.

Do you know how to determine the antiderivative of r^2 - y^2, with respect to y?

If so, then evaluate the definite integral in the usual way by replacing y with the expression d - r (as the upper bound) and with the expression -r (as the lower bound).

If you do not know how to determine the antiderivative of r^2 - y^2, with respect to y, then let me know.

You did not ask any questions. You did not make any statements about what you already know.

Therefore, I am not able to determine at what point in this exercise you're stuck.
 
i was trying to solve it as a circle where r^2=X^2 + Y^2

then x= sqrt of (r^2 - y^2) which is the original integral

then i got integral of X dy
then i took u=x du = dx
dv=dy v=y

then applied
uv- integral vdu

is that right or just a mess
thank u again
