Explanation:
Given that the diameter of the toy ball is 12.5 inches
We need to determine the volume of the toy ball.
The radius of the toy ball is given by



Thus, the radius of the toy ball is 6.25 in
The volume of the sphere can be determined using the formula,

Substituting the values, we get,

Multiplying, we get,

Substituting
, we have,

Simplifying, we get,

Thus, the volume of the sphere is

The answer is: [A]:
_________________________________________________
input: number of rowers number of rowers in the rowboat;
output: speed of the rowboat ;
_________________________________________________
NOTE: The input would be the independent variable and plotted on the "x-axis" of the graph; and the output would be the dependent variable and plotted on the "y-axis" of the graph.
