Suppose the circumference of a crop circle is 150.7968 hectometers (hm). what's the radius of the circle? (use π = 3.1416.)
a. 24 hm
b. 96 hm
c. 48 hm
d. 16 hm

How do i do this? i don’t understand

The domain of a function can be represented by which one of the following options? o a. a set of output values o b. a set of f(x) values o c. a set of input values o d. a set of both input and output values

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
