Question

Help me please!!!!!!

Answer 1

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.

Answer 2

As it shows, the area formula of a circle is $\pi r^{2}$.

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.

$\pi 13^{2}$

From there, the next step is to square our value following PEMDAS.

$\pi169$

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 $cm^{2}$.

Hope this helped! :)
