a. When two variables change in the same direction, one remaining larger than the other by the same factor - direct relationship
b. To insert between neighboring points or estimate by taking an average of known values - interpolate
c. A relationship between two variables in which the product remains constant. When one variable increases the other decreases in proportion so that the product is unchanged - inverse relationship
We know is a semi-circle, so let us use the equation for the area of a circle instead, and then, half it so, the diameter is 1100, meaning the radius is half that, or 550
