Answer:

72 cm

Step-by-step explanation:

Find the radius using the given information

308=1/2(πr^2)

r^2=616/π

r=14

The perimeter is πr + 2r so plug in 14

π(14) + 2(14)

43.96+28=71.96

Find the product.<br> (z + 3i)(z − 3i)

Doss [256]

Answer:

First, we use distributive property:

$(z+3i)(z-3i)=z^2-3zi+3zi-9i^2$

Now, remember that $i^2=-1$ , then

$z^2-3zi+3zi-9i^2=z^2-9(-1)=z^2+9$

Then,

$(z+3i)(z-3i)=z^2+9$
