Problem of the week:
Icebergs are formed when part of a freshwater glacier falls into the sea.
The density of the iceberg is less than the density of the sea water so the iceberg floats.
Typically 90% of the iceberg is underwater.
Assume 90% of the volume of an iceberg is under water.
The visible part above sea level of a dome-shaped iceberg is modeled by a hemisphere whose diameter is 5 meters.
What is the total volume of the iceberg in cubic meters?
Express your answer to the nearest whole number.
