What shape is the cross-section of a sphere?
A circle.
What is the area of the cross section of a sphere that is 12 units from the center of the sphere?
That depends on how many units there are in the diameter of the sphere. * * * * * If the radius of the sphere is R units then the radius of the cross section is sqrt(R2 - 122) Therefore the cross sectional area is pi*(R2 - 122) square units.
If you cut a sphere with a vertical angled and horizontal slide what are the cross sections?
When a sphere is cut with a vertical angled plane, the cross-section will be an ellipse. If the sphere is then cut by a horizontal plane, the cross-section will be a circle. Thus, the combination of these two cuts results in an elliptical cross-section from the angled cut and circular cross-sections from the horizontal cuts at various heights.
What do you notice about the cross section of a solid sphere?
Every section of a solid sphere is a filled-in circle, i.e. a disk with zero thickness.
What shape has any cross- sections are circles?
any cross section of a sphere is a circle.
