Answer:

Step-by-step explanation:

The formula for the volume of a cylinder of base radius r and height h is

V = π·r²·h. Get the radius and height information from the original problem statement and substitute these values into this formula.

For example, if the radius is 3 cm and the height is 4.5 cm, then the volume of this particular cylinder is

V = π·(3 cm)²·(4.5 cm) = 127.2 cm³ (this is an EXAMPLE only)

What are the roots of the quadratic equation below?<br> x2 + 2x= -5

Answer:

No real root.

Complex roots:

$x = -1 \pm 2i$

Step-by-step explanation:

$x^2 + 2x = -5$

$x^2 + 2x + 5 = 0$

There are no two integers whose product is 5 and whose sum is 2, so this trinomial is not factorable. We can use the quadratic formula.

$x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}$

$x = \dfrac{-2 \pm \sqrt{2^2 - 4(1)(5)}}{2(1)}$

$x = \dfrac{-2 \pm \sqrt{4 - 20}}{2}$

$x = \dfrac{-2 \pm \sqrt{-16}}{2}$

Since we have a square root of a negative number, there are no real roots. If you have learned complex numbers, then we can continue.

$x = \dfrac{-2 \pm 4i}{2}$

$x = -1 \pm 2i$
