Discussion Topic You have probably studied circles in previous math courses and used formulas to measure the distance around a circle (circumference) and the space inside a circle (area). These formulas measure the circumference and the area of a full circle. In real life, we often aren't dealing with a full circle. For example, think about the shape of a slice of pizza or pie. Can you think of other real-life situations that include only part of a circle? How could you adjust the circumference and area formulas to measure part of a circle rather than the full circle
