471.24
Step-by-step explanation:
V=πr2h=π·52·6≈471.2389
I GOT U BRO THE ANSWER IS
5/18
A= P(1 + r)^n
where,
A= final balance
P= initial quantity
n= number of compounding periods
r= percentage interest rate
So,
P= $200
n= 6 years
r= 6%= 0.06
=$200(1 + 0.06)^6

Answer:
72.25 ft
Step-by-step explanation:
The function that models the height of the ball is

The maximum height occurs at:


We substitute t=2.125 to get:


The maximum height is 72.25 feet
