Answer: 3817.1 or 1215pi
Step-by-step explanation:
Volume = πr2h
= π×92×15
=1215π
= 3817.0350741116
For example: if there are two tens and 15 ones, you could take another ten out of the ones. this makes the adding less complicated
Given that height, h(t) of a tennis ball is modeled by the equation h(t)=<span>-16t^2 + 45t + 7, the time taken for the ball to reach maximum height will found as follows:
at maximum height:
h'(t)=0
but from the equation:
h'(t)=-32t+45=0
solving for t we get
t=45/32
t=1.40625~1.4 seconds
Thus the time taken to reach maximum height is 1.4 seconds

He has 87 cards then he gets 9 more which is 96, he then gives 16 away which is 80, then he is given 3 which is 83 he sells all 83 cards to the collector & the collector gives him $124.50 each card is worth $1.50
The answer is y=-5/2x+9 and the picture includes the equation and points. Hopefully, this helps.
