we know that
When circles have the same central angle measure, the ratio of measure of the sectors is the same as the ratio of the radii squared
.
so
rA²/rB²=A/B
where
rA-------> radius circle A
rB------> radius circle B
A------> area sector A
B------> area sector B
rB²=B*rA²/A-------> 6²*[40π]/[1
0π]-------> 144--------> rB=
√144
rB=12 m
the answer is
radius of circle B is 12 m
