INSECTS One particularly large ant hill found in 1997 measured 40 inches wide at the base and 18 inches high. What was the slope of the ant hill?

To find the slope of the ant hill, we can use the formula for slope, which is the rise (height) over the run (base radius). The height of the ant hill is 18 inches, and the base width is 40 inches, so the radius is 20 inches. Therefore, the slope is 18 inches (rise) divided by 20 inches (run), resulting in a slope of 0.9.
