V =


h
1. Find the radius.
8/2 = 4
2. Square the radius.

= 16
3. Multiply that by pi.
3.14 * 16 = 50.24
4. Multiply that by the height.
50.24 * 20 = 1004.8
5. Now find 60% of that.
1004.8 * 0.6 = 602.88
V = 602.88

Honestly, it's been a while since I've done this, but I believe this is the answer.
Area of a rectangle can be calculated by multiplying length times width.
15*9=135 ft^2
Answer:
<em>(n - 5)(n + 5) </em>
Step-by-step explanation:
a² - b² = (a - b)(a + b)
n² - 25 = n² - 5² = <em>(n - 5)(n + 5)</em>
Answer:
No, not really.
dividing 25 into 4 equal groups, equals 6.25.
So no, you can not divide 25 into 4 equal group.
If if was 25 into 5 equal groups, then yes.
