Answer 3

AB/radius= π/10,

radius =\(\large \frac{10 AB}{\pi}\)

Answer 4

area of circle = (radius\()^2 \pi\)
= \(\large( \frac{10 AB}{\pi})^2 \pi\)
= \(\large \frac{(10 AB)^2 }{\pi} \)

Answer 5

nw how to find area of sector :D

Answer 6

got it. its 1/20. Thanks ur the best like always xD

Answer 7

aww ok :)

Answer 8

YW :)

Answer 9
