@DivineSolar we are using 3.14 as pi thats usually what these types of equations call for.. but great catch
rebeccaxhawaii (rebeccaxhawaii):
okay then subtract 615.44 from 784 to get the area of the shaded area
DivineSolar (divinesolar):
I know, I like to be a dork sometimes hehe~
OpenStudy (asad786):
