Final answer:
Tommy's lollipop has an area of 12.56 square inches. This is calculated by using the formula for the area of a circle (πr²), substituting r with half of the diameter (2 inches), and multiplying the result by π.
Step-by-step explanation:
To calculate the area of a circle, or in this case, a round lollipop, you can use the formula for the area of a circle which is πr², where r is the radius. The radius is half of the diameter, so in this case, the radius would be 2 inches (since the diameter is 4 inches). Plugging the values into the formula we get, π*(2)².
Multiplying it out gives us 4*π (or 4*3.14 when using the provided value for π). The resulting area is about 12.56 square inches. So, Tommy's lollipop has an area of 12.56 square inches. It's important to remember these steps when dealing with questions about the area of a circle in the future.
