Which figure shows how a shape can be rotated about an axis to form a hemisphere?

A. (first choice)

Step-by-step explanation:

Examine all options:

A. The diagram shows the arc (1/4 from a circle). While rotating this arc about the given axis, we get the hemisphere.

B. The diagram shows the semicircle (1/2 from a circle). While rotating this semicircle about the given axis, we get the whole sphere.

C. The diagram shows the segment (perpendicular to the axis). While rotating this segment about the given axis, we get the circle (lying in a plane).

D. The diagram shows the segment. While rotating this segment about the given axis, we get the cone.

on your paper it doesn't say the answer but the the answer is altitude

step-by-step explanation:

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
