Answer:
602.88 cu ft.
Step-by-step explanation:
V = Bh where B is the area of the base, which is a circle in your problem.
Since the diameter is 8, the radius is 4.
So, B = 
V = Bh = 50.24(20) = 1004.8 cu ft = total volume of tank
60% of that volume is .60(1004.8) = 602.88 cu ft.

<u>Step-by-step explanation:</u></h3>
Here , two circles are given which are concentric. The radius of larger circle is 10cm and that of smaller circle is 4cm . And we need to find thelarea of shaded region.
From the figure it's clear that the area of shaded region will be the difference of areas of two circles.
Let the,
- Radius of smaller circle be r .
- Radius of smaller circle be r .
- Area of shaded region be

Answer:
In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle.
Step-by-step explanation:
Answer:
B. n / 4; 6
Step-by-step explanation:
Let
n = the unknown number
the quotient of a number and four
= n/4
When n = 24
The expression becomes
= n/4
= 24/4
= 6
B. n / 4; 6
Answer:
x=6
Step-by-step explanation:
Remember, the formula for area is the length times the width. So, if we know the width is 3, and we know the total area is 24, all we need to do is divide 24 by 3 to get 8. 8 is the split up side, the one that is x + 2. To find x, simply subtract 2 from 8. 8 - 2=6.
24/3=8
8-2=6
