The diameter of a quarter is about 1 in.

You trace around the edge of the quarter on a sheet of paper.
What is the area of the circle on the paper?

Use 3.14 as an approximation for π. Round your answer to the nearest tenth.

Answer: The area is going to be 0.8

Step-by-step explanation: The diameter is 1

You need the radius of the circle which is half the diameter. So the Radius(R) is 0.5.

After you find the radius of the circle to find the area of the circle you use the formula pie (R)^2. You are using 3.14

3.14(0.5)^2= 0.785

you then want to round your answer to the nearest tenth so the 8 turns the 7 into an 8.

So, the Area is 0.785 but after rounding it is 0.8.

Hope that helped :)
