A cylinder has a radius of 5 and height of 3. what is the volume

Lapatulllka [165]

Answer:

236 cubic units (to 3 significant figures)

Step-by-step explanation:

volume of a cylinder = $\pi$ r²h (where r = radius and h = height)

Therefore, volume = $\pi$ x 5² x 3

= $\pi$ x 25 x 3

= 75 $\pi$

= 236 cubic units (to 3 significant figures)

Which complex number has a distance of radical 17 from the origin on the complex plane?

Inga [223]

Answer: LAST OPTION

Step-by-step explanation:

The complex numbers shown have the form:

$a+bi$

By definition, the distance can the distance of the complex number from the origin on the complex plane can be calculated with the formula shown below:

$d=\sqrt{a^2+b^2}$

Substitute values of each option. Then:

1) $d=\sqrt{2^2+15^2}=\sqrt{229}$

2) $d=\sqrt{17^2+1^2}=\sqrt{290}$

3) $d=\sqrt{20^2+(-3)^2}=\sqrt{409}$

4) $d=\sqrt{4^2+(-1)^2}=\sqrt{17}$ (CORRECT OPTION)
