Answer:
Step-by-step explanation:
3
Formula to find the central angle is,

Where, s = arc length
r = radius
= central angle in radian.
According to the given problem,
r = 7 and
.
First step is to plug in these values in the above formula. So,

By simplifying.
Since 

s=14.65
Hence, arc length iss 14.65 feet.
Answer:
a8 = 512.
Step-by-step explanation:
This is geometric sequence with common ratio r = 2 and first term a1 = 4.
nth term = a1 r^(n-1)
So a8 = 4 2(^8-1)
= 4 * 2^7
= 4*128 = 512.
88 inches long would be the answer
Well, if there are 3 sheep for every 8 horses then there should be 15.75 sheep.
.......you divide 42 by 8 to find the number of horses (5.25) and then multiply that by 3 (15.75).
I hope this helps you.
