Answer:
not a function
Step-by-step explanation:
The formula for the sum of the a finite geometric series is this:
Sn = a((1-r^n) / (1-r))
The given values are:
n = 30
a = 0.5 mi
r = 1.10 (10% more each day)
S30 = 0.5 ((1-1.10^30) / (1-1.10))
S30 = 82.25 mi
After 30 days, he will have traveled 82.25 miles.
Answer: 20.52
Step-by-step explanation:
131.88 or jus do radius times 2 so 21+ 21 = 42.
42 x pi(3.14) = 131.88
