DETERMINE FORMULA OF VOLUME OF SPHERE
Tools and Materials:
Ball, cone from paper which has the diameter same with ball and the height same
with radius of ball, rice
Steps:
1. Fulfill the cone using rice then pour rice into a half of ball.
2. How many cone that is needed to fulfill a half of ball?
Volume of a half ball= ….. × Volume of a cone
= ……× ……………
= ………..
Hence, volume of ball = …………….
Volume of sphere = ………………………….
