In order to find the volume of the tank, you just need to use this formula :
V = π r^2 h
r = 101.5 ft (half the diameter)
h = 25 ft
V = π (101.5)^2 x 25
= 809462.5 ft^3
hope this helps
Answer:
Step-by-step explanation:
Your difference of perfect cubes formula is given as
and you have already correctly identified a as 
and b as 
. So we fill in the formula as follows:
and we simplify. Remember that
. It's important that you remember the rules.
Simplifying then gives us
That's it, so fill it in however you need to on your end. Learn the patterns for the sum and difference of cubes and it will save you a ton of headaches...promise!!
Answer:
2:30 pm
Step-by-step explanation:
In two hours (from 10am), she is 45 * 2 = 90 miles from vacation cabin.
From then on her average is still 45 mph and her husband's is 65 mph. So, husband catches her 20 miles (65-45=20) in every hour.
<em>The husband has to catch up 90 miles. How long would it take if he is catching up at 20 miles an hour?</em>
<em>90/20 = 4.5 hours</em>
<em />
<em>So husband starts at 10am and 4.5 hours form that time is 2.30pm</em>
Answer:
the negative reciprocal is -17/20
