Question

Find the area of a circle with a diameter of \color{green}{6}6start color green, 6, end color green.

Answer 1

Answer:

The area of the circle is $9 \pi\ units^{2}$  or  $28.26\ units^{2}$

Step-by-step explanation:

we know that

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=6/2=3\ units$ ----> the radius is half the diameter

substitute

$A=\pi (3)^{2}=9 \pi\ units^{2}$ -----> exact value

assume

$\pi=3.14$

$A=9(3.14)=28.26\ units^{2}$
