Ответ:
200 in^2
Step-by-step explanation:
The formula to a circle's area is pi*radius^2
The radius is given to you already
So all you need to do is plug in the radius into the formula using 3.14 for pi (as the problem asked you to)
3.14*8^2
You need to remember to use order of operations or PEMDAS for short:
Exponents come first:
8^2=64
Then multiply 64*3.14=200.96
The problem says to not round so 200.96 in^2 is your final answer
