Question

if a heap of wheat forms a girl whose diameter is 14 metre and height 5 metre find its volume find the slant height of the heap of wheat ?
​

Answer 1

so assuming the heap to be a cone

r= d/2=14/2=7m

h=5m

Vol. of heap(cone) = 1/3 π r² h

= 1/3 π 49×5

= 1/3 × 22/7 × 49×5

= 22×35/3

= 256.65 m³

l² = h²+r²

= 5²+7²

= 25+49

l² = 74

l=√74 m
