Sure, here are the steps to find the length of the arc AB:
- First, we need to find the angle of the sector. The formula for the area of a sector is (θ/360) * π * r², where θ is the angle in degrees and r is the radius. We know the area is 126 cm² and the radius is 12 cm. So we can set up the equa Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
