Answer:
10 ft²
Step-by-step explanation:
Recall that the volume of a uniform cylinder may be defined by the formula:
Volume = Base Area x Height
In our case we are given
Volume = 15 ft³ and Base Area = 1.5 ft
Substituting these known values into the formula gives:
Volume = Base Area x Height
15 = Base Area x 1.5
Base Area = 15 / 1.5
Base Area = 10 ft²
Answer: 6/14 and 42/99
Step-by-step explanation:
<h3>Answer: Choice D)

</h3>
===========================================
Explanation:
Use a calculator to find the decimal form of each of the following below (values are approximate; rounded to 2 decimal places)
- 2pi = 6.28
- sqrt(42) = 6.48
- sqrt(34) = 5.83
We see that the order of the decimal values is: 5.83, 6, 6.28, 6.48
So the order of the terms, from smallest to largest, is 
50 secs
as $90÷5hrs= 18 $ per hrs
$18÷60min=$0.30 per min
$0.30÷60sec=$0.005 per sec
$0.25÷$0.005= 50sec to make $0.25
so 50sec is the answer
