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<span>.
</span>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<span>0π]-------> 144--------> rB=</span>√144
rB=12 m
the answer is
radius of circle B is 12 m
Answer:
23/30 are blue balloons. 23/30 = 76.7 = 0.767. I would say that 0.767 is the answer!
Answer:
D
Step-by-step explanation:
If the function is even then
f(x) = f(- x)
Given
f(x) = then
f(- x) = =
Since f(x) = f(- x) then f(x) is even
