Question

Which of the following could be used to calculate the area of the sector in the circle shown above?
A. π(15in) 40 over 360
B. π(40in)2 15 over 360
C. π(15in)2 40 over 360
D. π(40in) 15 over 360

Answer 1

When I do these, I set up a proportion:

40/360 = x/( pi *15^2)

That will give the area of the sector x.
