Label your answer.

A cereal bowl has a circumference of 25 cm. What is the diameter of the cereal bowl?

Label your answer. Use 3.14 for π and round to the nearest hundredth.

Find the area of the circle shown below.

Label your answer. Use π = 3.14

(When you are not given units such as "cm" or "inches", just use "units" or "square units" as your label)
