Sandpile

Auto sprinkled with sand to an approximately conical shape. Workers wanted to determine the volume (amount of sand) and therefore measure the base's circumference and the length of both sides of the cone (over the top).

What is the sand cone's volume if the circumference of the base is 6 m and the length of the two sides together 6 m?

Correct result:

volume is:  2.7 m3

Solution:

r=62π=0.95 m V=13Sv=13πr2624r2=2.7 m3
