Answer:
Solving for Area of Circle is usually the easiest for me. The answer is 530.66 cm squared.
Step-by-step explanation:
We know that the formula for solving the area of a circle is A = pi radius squared.
Substitute the radius, (in this case is 13), into the formula.
A = pi radius squared.
A = 13 squared pi
Then, do 13 times 13, since 13 is being squared.
13 times 13 = 169
A = 169 pi
Then we know that we are using 3.14 for pi. Multiply 169 to 3.14
A = 169 times 3.14
A = 530.66
Hope this helps. Sorry if I was wrong.
As it shows, the area formula of a circle is [tex]\pi r^{2}[/tex].
Since 13 takes up half the circle connecting through the center, we know that value must be our radius, and we can substitute it in.
[tex]\pi 13^{2}[/tex]
From there, the next step is to square our value following PEMDAS.
[tex]\pi169[/tex]
And finally, we can multiply to solve using 3.14 for pi.
530.66
Therefore, the area of the circle is equal to 530.66 [tex]cm^{2}[/tex].
Hope this helped! :)
