3/10 is the probability of them losing.
$5 each car
3 hours = 12 cars
÷3 ÷3
1 hours = 4 cars
×8 ×8
8 hours = 32 cars
32 cars × $5 per car =
$160
They earned $160 in 8 hours, from washing 32 cars.
<u>Given </u><u>:</u><u>-</u>
- Radius of cylinder is 7ft.
- Height is 12ft .
<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>
- The volume of the cylinder .
<u>Solution</u><u> </u><u>:</u><u>-</u>
As we know that the volume of the cylinder is ,
Volume = πr²h
On substituting the respective values ,
Volume = 3.14 * (7ft)²*12ft
Volume = 3.14*49ft²*12ft
Volume = 1846.32 ft.³
<u>Hence </u><u>the</u><u> required</u><u> answer</u><u> is</u><u> </u><u>1</u><u>8</u><u>4</u><u>6</u><u>.</u><u>3</u><u>2</u><u> </u><u>ft³</u><u>.</u>
