Step-by-step explanation:

step 1. the area of a circle is A. A = (pi)r^2.

step 2. if the diameter is 8 cm then the radius is 4 cm.

step 3. A = (pi)4^2

step 4. A = 16(pi) = 50.24 cm.

Answer:

Step-by-step explanation:

A= $\pi$ $r^{2}$ Diamter is half the radius so the radius is 4

A= 3.14 times $4^{2}$ $4^{2}$ = 16

A= 3.14 times 16

A=50.24

rounded answer will be 50.2

What is the completely simplified equivalent of 2/(5+i)?

Bezzdna [24]

namely, let's rationalize the denominator in the fraction, for which case we'll be using the conjugate of that denominator, so we'll multiply top and bottom by its conjugate.

so the denominator is 5 + i, simply enough, its conjugate is just 5 - i, recall that same/same = 1, thus (5-i)/(5-i) = 1, and any expression multiplied by 1 is just itself, so we're not really changing the fraction per se.

$\bf \cfrac{2}{5+i}\cdot \cfrac{5-i}{5-i}\implies \cfrac{2(5-i)}{\stackrel{\textit{difference of squares}}{(5+i)(5-i)}}\implies \cfrac{2(5-i)}{\stackrel{\textit{recall }i^2=-1}{5^2-i^2}}\implies \cfrac{2(5-i)}{25-(-1)} \\\\\\ \cfrac{2(5-i)}{25+1}\implies \cfrac{2(5-i)}{26}\implies \cfrac{5-i}{13}$
