Sonbull [250]

Answer:

x = 2.7

Step-by-step explanation:

The given equation is :

$(3x)^2-10=56$

We need to solve it for x.

It can be rewrite as follows:

$9x^2-10=56$

Adding 10 to both sides,

$9x^2-10+10=56+10\\\\9x^2=66\\\\x=\sqrt{\dfrac{66}{9}}\\\\x=2.70$

So, the value of x is equal to 2.7.

If the radius of the right cylinder is 5 in and the radius of the oblique cylinder is 4 in, they will have the same volume as lo

steposvetlana [31]

Answer:

False

Step-by-step explanation:

The volume of a right cylinder is given by the formula:

$V=\pi r^2h$

And the volume if a oblique cylinder is <em>also</em> given by the formula:

$V=\pi r^2h$

Regardless of the height, if the radius are different, then the volume would not be the same.

Algebraically:

$\pi(4)^2h\neq\pi(5)^2h\\16\pi\neq25\pi$
