3. Find the volume of a hemisphere with a radius of 17 inches. Round to the nearest tenth​

Write a recursive sequence that represents the sequence defined by the following explicit formula:

The general form of the quetion of a circle is ax^2+by^2+cx+dy+e=0 where a=b=0 if the circle has a radius of three units and the center lies on the y axis which set of values of a, b, c, d, and e might correspond to the circle

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.
