Let
rA--------> radius of the circle A
rB-------> radius of the circle B
LA------> <span>the length of the intercepted arc for circle A
</span>LB------> the length of the intercepted arc for circle B
we have that
rA/rB=2/3--------> rB/rA=3/2
LA=(3/4)<span>π
</span>
we know that
if <span>Both circle A and circle B have a central angle , the ratio of the radius of circle A to the radius of circle B is equals to the ratio of the length of circle A to the length of circle B
</span>rA/rB=LA/LB--------> LB=LA*rB/rA-----> [(3/4)π*3/2]----> 9/8π
the answer is
the length of the intercepted arc for circle B is 9/8π
Answer:
7/6
Step-by-step explanation:
divide both the numerator and denominator by 8
AB is a diameter of the circle, so it divides circle into two semicircles.
Inscribed Angle Theorem:
The measure of an inscribed angle is half the measure of the intercepted arc.
An especially interesting result of the Inscribed Angle Theorem is that an angle inscribed in a semi-circle is a right angle. That's why m∠<span>AQB=m∠</span><span>ASB=m∠</span><span>ALB=m∠</span><span>ATB=m∠</span><span>ARB=90°.</span>
It is impossible to find measure of ∠<span>BWD, its measure depends on measure of a central angle ∠WDB. </span>
Answer:
90 chickens
Step-by-step explanation:
91 chickens are there, subtract 1 chicken there 90 left
91 - 1 = 90
