Answer 1

Answer:

Very last choice is the answer.

Step-by-step explanation:

Remark

The thing that is most important is that the horizontal line connect h and the radius is parallel to the cut of the sphere if it was placed right in the middle. That line swings around as though the center was a pivot.

Solution

• So what you have is a circle when that line goes around that part of the sphere.
• To find the length of that line, use the Pythagorean Theorem. Call the line r1.
• r1 ^2 = r^2 - h^2
• So the area is pi * r1^2
• Area = pi (r^2 - h^2)
• The very last one is the answer.
