The volume of a cone is approximately 423.9 cubic inches of the height is 5 what is the radius of the base

1 answer:

4 0

Cone Volume = (π • r² • h) ÷ 3

radius^2 = 3 * cone volume / PI * height

radius^2 = 3 * 423.9 / 3.14159 * 5

radius^2 = 80.9590048351 

radius = 8.9977222026

What is the product of 2p+q and -3q-6p+1

Arlecino [84]

Hey there,

The question is to find the product of the two factors (2p + q)(-3q - 6p + 1).

Now we just multiply across:

-6pq - 12p² + 2p -3q²- 6pq + q

Now we combine like terms:

-12p² - 3q² + 2p + q

So the result would be -12p² - 3q² + 2p + q.

Hope I helped,

Use radical notation to rewrite each expression and simplify 9 3/2

scoundrel [369]

Answer:

$9^{\frac{3}{2}}=\sqrt{9^3}=27$

Step-by-step explanation:

The fractional exponent m/n is often translated to radical form as ...

$x^{\frac{m}{n}}=\sqrt[n]{x^m}$

In this case, I find it easier to evaluate as ...

$x^{\frac{m}{n}}=(\sqrt[n]{x})^m=\boxed{(\sqrt{9})^3=3^3=27}$
