Sub in the 5 for x and the 8 for y 6x5-8=22
Because 3/5 and 5/3 make a product of 1, so you have one x on the right side.
New volume is given by:
New volume=(old volume)×(4×2/9×2/9)
simplifying the above we get:
New volume=(old volume)×16/81
Thus the new volume is 16/81 times the old volume
old volume=πr²h
Hence:
Answer:16/81πr²h
<u>24</u> = <u>30</u>
x = 100
<u>30x</u> = <u>2400</u>
30 = 30
x = 80
