I am given a circle and one section says it is four sevenths and the other part is one third, and it is asking me to determine which what the shaded part of the circle is. I do not know how to do this.

hello there welcome to study pool


1) section=4/7

total sum of sections=1

so 4/7+shaded area=1

shaded area=1-4/7

=3/7



2) part=1/3

total sum of sections=1

shaded area=1-1/3

=2/3
