Answer:
Curved surface area of a cone =πrl.
3.142×8×15=377.04cm
We can figure out how many numbers there are from 368 to 500 by subtracting.
500 - 368 = 132
Now, we need to get it in word form. This can be done by looking at the place value of each number.. So your answer would be:
1 hundred, 3 tens, and 2 ones.
The original functions are: f(n) = 500 and g(n) = [9/10]^(n-1)
A geometric sequence combining them is: An = f(n)*g(n) = 500*[9/10]^(n-1):
Some terms are:
A1= 500
A2 = 500*[9/10]
A3 = 500*[9/10]^2
A4 = 500*[9/10]^3
....
A11 = 500*[9/10]^10 ≈ 174.339
Answer: the third option, An = 500[9/10]^(n-1); A11 = 174.339
