Question

A circle has its center at the origin of a coordinate plane. If you were to isolate one-quarter of the circle in Quadrant III and rotate that quarter about the x-axis, what three-dimensional object would be formed?(1 point)
Responses

a sphere
a sphere

a cone
a cone

a hemisphere
a hemisphere

a cylinder

Answer 1

When you isolate one-quarter of the circle in Quadrant III and rotate that quarter about the x-axis, you would form a hemisphere. This is because you are essentially rotating a semicircular shape (the quarter circle in Quadrant III) about the x-axis, resulting in a three-dimensional shape that is half of a sphere.

So the correct answer is:

**a hemisphere**
