How can integrals be used to find areas and volumes in calculus?

In calculus, integrals are used to calculate the area under a curve and the volume of a solid. Through the process of integration, students can find the total accumulation of quantities such as area, volume, and even distance traveled. By understanding how to set up and solve integrals, students in Grade 7 can apply these concepts to real-world problems, making connections between mathematics and the world around them. As they progress to Calculus AB, these foundational skills will become essential in solving more complex problems related to areas and volumes.
