Evaluate the integrals for f$($x$)$ shown in the figure below.

The two parts of the graph are semicircles.

a$\backslash$int$\_0^22$f$($x$)$dx$=$

b$\backslash$int$\_0^65$f$($x$)$dx$=$

c$\backslash$int$\_1^42$f$($x$)$dx$=$

d$\backslash$int$\_1^6|4$f$($x$)|$dx$=$

The answers in the boxes are incorrect.
