1. Find the area of the sector by multiplying the area of the circle by the ratio of the _________________________ to 360. 2. Subtract the area of the triangle from the area of the sector.

A sector is the fraction of the whole circle determined by its central angle. Multiply the circle’s area by the measure of the central angle divided by 360; then subtract the triangle’s area as directed. The correct choice is “measure of the central angle.”
