To solve this we are going to use the formula for the area of a circle: $A= \frac{1}{4} \pi d^2$
where
$A$ is the area of the circle
$d$ is the diameter of the circle

We know from our problem that the area of our circle is 10 inches long, so $d=10in$ . Lets replace that value in our formula to find $A$ :
$A=\frac{1}{4} \pi (10in)^2$
$A=78.54in^2$

We can conclude that the correct answer is: 78.54 square inches, or in centimeters: 506.7 square cm.

Step-by-step explanation:

Given that, a physics exam consists of 6 open-ended problem and 9 multiple choice questions.

The order of choosing does not matter.

So,we use combination to find ways.

The ways to choose 6 multiple choice from 9 is= $^9C_6$
