Answer:
Step-by-step explanation:
The diameter of the top of the coffee mug which the baker uses to cut out circular cookies from the big sheet of cookie dough is 8 cm.
Radius of the coffee mug is diameter of the coffee mug/2.
Radius of the coffee mug
= 8/2 = 4cm
The area of the circular mug is expressed as
Area = πr^2
Where π is a constant whose value is 3.14
Therefore,
Area of the top of the circular mug = 3.14 × 4^2 = 3.14 × 16 = 50.24 cm^2
The area of the top of the circular cup is the same as the area of each cookie. Therefore,
The area of each cookie is 50.24 cm^2

The equation to find percent error is

where actual is the value that actually came out (in this case, 11.5 km) and theoretical is the value that was supposed to come out (in this case, 10 km). Just plug in the numbers and simplify.

So, the true answer would be 15%. Apparently, the question you're asking takes 11.5 as the theoretical and the 10 as the actual (which I personally disagree with)
If you plugged in the numbers that way, the answer comes out to 13.04%. So, the correct answer for your answer choices is c. 13%
