From the meaning of the question: to find the total weight of grass in the haystack, the volume of cone+the volume of cylinder is required first.

The volume of the cone is set to v 1, and the volume of the cylinder is set to v2.

V 1= 1/3 The x height of the bottom area is known as 6.24m, that is, 2πX R = 6.24, so R = 6.24/2π bottom area =piR2=3. 1 m2, so V1=/kloc-0.

V2= bottom area x height. Similarly, it is known that the perimeter of the bottom is 4.7 1m, that is, 2πx r = 4.7 1, so r=4.7 1/2pi bottom area =πR2 = 1.766 m2, so v2 =1.766m2.

Total weight of grass = 160x(0.62+2.649)=523kg. I hope I can help you.
