Lisa runs approximately 5 and 5 / 9 yards per second.
Okay so, the formula we can use for this problem will be x= 410/.82, x being the original price of the TV. The .82 was figured to make up for the 18% lost from the original price. 410/.82=500. so the original price of the TV would be $500. To check our answer we can multiply 500 by the sale price and subtract that amount from the original $500. Like so: 500-(500*.18)=410.
Volume of cylinder = (pi)r^2 • h
So with the numbers, it’s:
V = (3.14)12.5^2 • 30
V = (3.14)156.25 • 30
V = 490.625 • 30
V is about 14,718.75
Since I rounded, the answer for your problem is “about 17,671 cubic feet.”
Hope this helped!
