V=πr²(1/3)(h)
d=6, therefore r=3 and
90=(3)²(1/3)(h) ... I didn't include the pi because it isn't in the answer
90=3h
h=30
Answer:
The height of the ball is less than 17 feet for t > 2 seconds.
Step-by-step explanation:
The height of the ball after t seconds is given by the following equation:
For which interval of the time is the height of the ball less than 17 feet
This is t for which:
So
Multiplying by -1
The height of the ball is less than 17 feet for t > 2 seconds.
8/0.61=13.114… then round if needed
