Question 999367: To carry their candy, Ariel, Ollie and Eden each have a bucket that looks like a pumpkin. It is completely spherical in shape with a straight slice across the top of the bucket that creates a circular opening for dropping in candy. If the radius of the bucket is 6 inches and the height, measured from the base of the bucket to the open top, is 9 inches, what is the area of the circular opening of the bucket, in square inches? Express your answer in terms of pi.

You can put this solution on YOUR website! To carry their candy, Ariel, Ollie and Eden each have a bucket that looks like a pumpkin. It is completely spherical in shape with a straight slice across the top of the bucket that creates a circular opening for dropping in candy. If the radius of the bucket is 6 inches and the height, measured from the base of the bucket to the open top, is 9 inches, what is the area of the circular opening of the bucket, in square inches? Express your answer in terms of pi.
----
Sketch the picture
From the center to the opening is 9-6 = 3 in
From the center to the edge of the opening is 6 in
-----
Draw that triangle including the radius of the opening.
radius = sqrt(6^2-3^2) = sqrt(36-9) = sqrt(27) in
-----
Ans: Area of opening = pi*radius^2 = 27pi sq in
