Karl has finished harvesting his barley and stored it short-term in a conical pile in his yard.
Karl’s auger is 41 ft long and the pile has a diameter of 75 ft.
:
a. Find the height of Karl’s pile using the Pythagorean Theorem.
Round to one decimal place.
A right triangle formed by the height, the radius (37.5) and the 41' augar is the hypotenuse
h^2 + 37.5^2 = 41^2
h^2 = 1681 - 1496.25
h^2 = 275.75
h = sqrt%28275.75%29
h = 16.6 ft is the height
< >
b. Find the volume of barley in Karl’s pile to the nearest cubic foot.
the Volume of a cone: V = 1%2F3*pi%2Ar%5E2%2Ah
V = 1%2F3*pi%2A37.5%5E2%2A16.6
V = 24,456 cu/ft
