Answer:
C
Step-by-step explanation:
Try each one using the formula for the volume of a cylinder, pi * r^2 * h:
A. 3.14 * 12^2 * 5 = about 2261 which does not equal 565
B. 3.14 * 10^2 * 4 = about 1256 which does not equal 565
C. 3.14 * 6^2 * 5 = about 565 which is correct!
D. 3.14 * 6^2 * 10 = about 1130 which does not equal 565
Therefore C is the right answer.

Answer:
b = 3 or -3 i suppose
Step-by-step explanation:
A) <span>Scale factor of the smaller pyramid to the larger pyramid in simplest form:
</span>6 m / 12 m = 1/2
b) <span>Ratio of the areas of the bases of the smaller pyramid to the larger pyramid:
</span><span>(1/2)^2 = 1/4 </span>
c) <span>Ratio of the volume of the smaller pyramid to the larger:
</span><span>(1/2)^3 = 1/8 </span>
d) <span>Volume of the smaller pyramid:
</span>(1/8) * 400 m^3 = 50 m^3
Answer:
a(a - b)
Step-by-step explanation:
<u>given </u><u>polynomial</u>: a²- ab - 8a + 8a
We can first simplify this answer by removing like terms,
- 8a + 8a = 0
so we have a²- ab in. the simplest form
we can take this one step further and factor out the a (not simplest form)
a time a = a²
a times b = ab
hence, a(a - b)
