Answer:
C) 500.83
Step-by-step explanation:
Surface area for a cylinder formula:
SA = 2πrh + 2πr²
Given:
d = 11
r = d/2 = 11/2 = 5.5
h = 9
Work:
SA = 2πrh + 2πr²
SA = 2(3.14)(5.5)(9) + 2(3.14)(5.5)²
SA = 310.86 + 2(3.14)(30.25)
SA = 310.86 + 189.97
SA = 500.83
Answer:
I think it is but not 100% sure

Step-by-step explanation:
Given
Every other minute
Required
Determine the recursive function
Let the number of minutes be represented with n.
The initial condition can be represented as:
--- i.e. 3 friends initially at the first minute
At every other minutes:
i.e 2 minutes upwards
This means that n follows the following sequence
Note that the difference between each term is 1.
This means that recursive function has to be defined backwards i.e.
Where k = 2
i.e. The number of friends that received the video from each friend
So, we have:
Hence, the recursive function is:
;
Answer:
OB - Older Brother
YB - Younger Brother
A) OB -YB = 4
B) OB * YB = 96
B) OB = 96 / YB
Multiplying A) by -1
A) -OB + YB = -4 then we add B)
B) OB = 96 / YB
YB = -4 + 96 / YB
Multiplying both sides by YB
YB^2 = -4YB +96 then re-arranging
YB^2 + 4YB -96 = 0 solving by quadratic equation
AS OF 5 years AGO:
Younger Brother's age = 8
Older Brother's age = 12
NOW THEIR AGES ARE:
8 + 4 = 12 YB and
12 + 4 = 16 OB
