Answer:
Volume=469cm³
Step-by-step explanation:
[tex]
Volume,V=Volume Cone + Volume\ of Hemisphere\\\\
Volume Cone,V1=\pi*r^2*\frac{h}{3}=\pi*4^2*\frac{12}{3}\\ \\
=201.06cm^3\\
Volume of Hemisphere,V2=2*\pi*\frac{r^3}{3}\\
=2*\pi*\frac{4^3}{3}=268.083cm^3\\
Volume=V1+V2=201.06+268.08\\
=469cm^3

<h2><u>Simplifying</u></h2>
<h3>x - (-6x)</h3>
To determine the answer, the first step is to apply distributive property.
Why it became positive? Notice that - (-6x), there is a negative sign inside and outside the parentheses. Since both of them are negative, we can say that when two negative numbers are multiplied together, it will became positive.

The compound interest formula:
A = P · ( 1 + r/n ) ^(n t)
where: P = $50, r = 0.06, n = 12, n t = 12 · 3 = 36;
A = 50 · ( 1 + 0.06/12) ^(36) =
= 50 · 1.005^(36) = 59.834 ≈ $59.83

Answer:
$612
Step-by-step explanation:
Each side of the square garden is 17 meters, and fencing costs $9 per meter. "Around" is the key word, as it indicates perimeter. So, we just need to account for each side of the garden, and not the entirety of the garden. So,
17 · 9 = 153
This means that to cover one side of the garden, it would cost $153. Now, we just need to account for all sides of the garden.
153 x 4 = 612
