What is the definition for Coplanar

Step-by-step explanation:

Here, "co" means "shared."  Two lines are coplanar if both lie in the same plane (in which case there are three possibilities:  the lines intersect in one point, the lines coincide (are one and the same), or the lines never intersect (in which case we call them "parallel."

Suppose we take a look at a three-dimensional space with perpendicular x-, y- and z-axes.  If we let one of these three variables be a constant, then the resulting area is a plane (with two-dimenions).  if we held z constant, then the plane would be the xy plane, and any two lines lying entirely in this plane are deemed to be "coplanar:"  they lie in the same plane.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
