Sector area = 0.5 * r^2 * angle (in radians)
so:
16 pi = 0.5 * r^2 * (90*pi/180)
r^2 = 16 pi /(0.25 pi) = 64
r = 8
therefore it would be d
20\2=10
10\2=5
5\2=2.5
2.5\2=1.25
Answer:11 and 27
Step-by-step explanation:
11+16=27 and they are 16 years apart and because it says 5 years 27+5=32 and if you add 5 to 11 you get 16 and 16+16=32
I belive the answer would be B if not im sorry
