When the midpoints of adjacent sides of a quadrilateral are connected by segments, these segments form a
a.) parallelogram
b.) rhombus
c.) square
d.) trapezoid

Option 'a' is correct.

Step-by-step explanation:

Since we have given that

When the midpoints of adjacent sides of quadrilateral are connected by segments.

These segments form a parallelogram.

These segments  form parallelogram irrespective of kind of quadrilateral.

Since all sides of these segments are opposite to each other.

So, Option 'a' is correct.

the answer to this question is in the pic

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
