Question

MEDAL GIVEN HELP!
Calculate the area of the shaded sector in square inches.
A. 5.5 in2
B. 1.09 in2
C. 4.26 in2
D. 8.5 in2

Answer 1

for a full circle the area = pi*r^2
that means when the angle=360, area = pi*r^2
when angle=1; area= pi*r^2/360
when angle =25 area= 25*p*r^2/360

where r=d/2= 12.5/2

Answer 2
