What is the volume of the cylinder below radius 6 height (straight up) 8 height (slanted) 9

larisa [96]

Hey!

The formula for finding volume of a cylinder is: π · r² · h

$r = 6 \\ r^{2} = 6 \times 6 = 36$

$h = 8$

Now multiply

$\pi \times 36 \times 8 = 288\pi$

Your answer is C)288π units³

Good luck and hope this helps! :)

Solve the logarithmic equation for x.

aev [14]

Answer:

x = 2 or x = 4

Step-by-step explanation:

Solve: 2 log x = log 2 + log(3x - 4)

log (x^2) = log 2 + log (3x - 4)

log (x^2) = log [2*(3x - 4)]

x^2 = 2*(3x - 4)

x^2 = 6x - 8

x^2 - 6x + 8 = 0

factor:

(x - 2 )(x - 4) = 0

x = 2 or x = 4

Question 83 true or false and why ? plz ryt answer thanks

Vikki [24]

The answer is false.

The formula for the SA of a cone is $\pi r^{2}+\pi rl$ where r is the radius of the base and l is the slant height.
Since we have both the slant's height and the radius of the base we can answer this just by plugging numbers in;
$SA=\pi r^{2}+\pi rl\\
SA=\pi (2^{2})+\pi (2)(6)\\
SA=4\pi+12\pi\\
SA=16\pi\\$
$16\pi$ ≈50.2654...

So your answer is false.
