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.
