Question 4533
ok...2 circles with radii 4.5 and 6 inches.


area of circle = {{{pi*r^2}}}


so, area 1 = {{{pi*4.5^2}}} and so, area 2 = {{{pi*6^2}}}


these, together are {{{20.25pi + 36pi}}} --> {{{56.25pi}}} inches^2


Using the calculater, this is 176.71 inches^2. Hopefully, this is the answer in your book? If not, there is a typo in your book :-)
