Help solve this problem!
z=14i+12.1
Re(z)=?
Im(z)=?

Re(z)=12.1,

Im(z)=14i

Step-by-step explanation:

Re(z) is the real part of the complex number. It always stands without i (imaginary unit), thus,

Re(z)=12.1.

Im(z) is the imaginary part of the complex number. It always stand with imaginary unit i. Hence,

Im(z)=14.

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice
