Let
rR--------> radius of the circle R
rS-------> radius of the circle S
LR------> the length of the intercepted arc for circle R
LS------> the length of the intercepted arc for circle S
we have that
rR=2/3 ft
rS=3/4 ft
rR/rS=8/9--------> rS/rR=9/8
LR=(4/9)π ft
we know that
if Both circle R and circle S have a central angle , the ratio of the radius of circle R to the radius of circle S is equals to the ratio of the length of circle R to the length of circle S
rR/rS=LR/LS--------> LS=LR*rS/rR-----> [(4/9)π*9/8]----> (1/2)π ft
the answer is
the length of the intercepted arc for circle S is (1/2)π ft
Answer: 870
Step-by-step explanation:
If the hiker starts at 80 feet above sea level and hikes 790 feet higher it would be 80 plus 790 which equals 870 feet above sea level.
Answer:
4+8=12
Step-by-step explanation:
Add them together and subtract so it would be 3/10+2/10=5/10 1-5/10=5/10
The answer is 5/10
Answer:
5 = 8
Step-by-step explanation:
5 - 2 + 2 = 8
= 3 + 2 = 8
= 5 = 8
