Answer:

V= 42.41

Step-by-step explanation:

$V = \pi r^{2}\frac{h}{3}$

where r is the radius = 3 and h is the height = 4.5

$V= \pi$ × $3^{2}$ × $\frac{4.5}{3}$

V = 42.41

Answer:

x= -6

Step-by-step explanation:

-2x-14=-2

We move all terms to the left:

-2x-14-(-2)=0

We add all the numbers together, and all the variables

-2x-12=0

We move all terms containing x to the left, all other terms to the right

-2x=12

x=12/-2

x=-6

Condense the expression to the logarithm of a single quantity.<br><br>

vladimir1956 [14]

Answer:

$\log _3\left(\frac{x^{\frac{1}{2}}}{\left(y+8\right)^2}\right)$

Step-by-step explanation:

-> Apply log rules

$\log _3\left(x^{\frac{1}{2}}\right)-2\log _3\left(y+8\right)$

$\log _3\left(x^{\frac{1}{2}}\right)-\log _3\left(\left(y+8\right)^2\right)$

-> Apply basic math rules

$\log _3\left(\frac{x^{\frac{1}{2}}}{\left(y+8\right)^2}\right)$
