Find the volume of the sphere with a diameter of 22 and round to the nearest 10

maksim [4K]

Answer:

$\huge\boxed{\sf Volume = 16728.8 \ units^3}$

Step-by-step explanation:

Diameter = 22 units

Radius = 11 units

$\rule[225]{225}{2}$

$\sf Volume = \frac{4}{3} \pi r^3\\\\Volume = \frac{4}{3} (3.14)(11)^3\\\\Volume = \frac{4}{3} (3.14)(1331)\\\\Volume = \frac{4}{3} (4184.5)\\\\\bold{Volume = 16728.8 \ units^3}$

$\rule[225]{225}{2}$

Hope this helped!

Hi, can someone please help, and possibly explain the answer please.

mr_godi [17]

Answer:

$x=\frac{-(-2)\±\sqrt{(-2)^2-4(3)(0)} }{2(3)}$

Step-by-step explanation:

Quadratic formula: $x=\frac{-b\±\sqrt{b^2-4ac} }{2a}$ when the equation is $0=ax^2+bx+c$

The given equation is $1=-2x+3x^2+1$ . Let's first arrange this so its format looks like $y=ax^2+bx+c$ :

$1=-2x+3x^2+1$

$1=3x^2-2x+1$

Subtract 1 from both sides of the equation

$1-1=3x^2-2x+1-1\\0=3x^2-2x+0$

Now, we can easily identify 3 as a, -2 as b and 0 as c. Plug these into the quadratic formula:

$x=\frac{-b\±\sqrt{b^2-4ac} }{2a}\\x=\frac{-(-2)\±\sqrt{(-2)^2-4(3)(0)} }{2(3)}$

I hope this helps!

What is Ten percent of a number added to that number?

rodikova [14]

Let x be this number 10% of the number x is (10%)(x) → 0.1x
Then 10% of a number x, added to that number is (1.1x):

x + 0.1x = x(1+0.1) = x(1.1) = 1.1x
