Answer:

r = 10.72 cm

Step-by-step explanation:

h = 6 cm

Volume of cone = 722 cubic cm

$\frac{1}{3}\pi r^{2}h=722\\\\\frac{1}{3}*3.14*r^{2}*6=722\\\\r^{2}=\frac{722*3}{3.14*6}\\\\r^{2}=114.97\\\\r = \sqrt{114.97}\\\\r = 10.72$

A complex number has a real and an imaginary part

$4 + 9i$ is a complex number

A complex number is represented as:

$a + bi$

Where:

$a \to$ real

$bi \to$ imaginary

By comparing the options to $a + bi$ ;

$-7$ and $2 + \sqrt 5$ are not complex numbers

This is so because they do not have imaginary parts

However,

$4 + 9i$ is a complex number

Because; 9i is imaginary
