a heap of rice is in the form of a cone of base diameter 24m and height 3.5, find the volume of the rice . how much canvas cloth is required to just cover the heap
Area of Canvas Cloth required (A) = Curved/Lateral Surface Area of the Cone = [tex]\pi \: × \: rl[/tex] A = πrl r = 12 m h = 3.5 m [tex]l \: = \: \sqrt{ {r}^{2} \: + \: {h}^{2} } [/tex] [tex]l \: = \: \sqrt{ {(12)}^{2} \: + \: {(3.5)}^{2} }[/tex] [tex]l \: = \: \sqrt{144 \: + \: 12.25} \: = \: \sqrt{156.25} \: = \: 12.5[/tex] l = 12.5 m A = π × 12 m × 12.5 m A ≈ 471.2389 m². Hence, 471.2389 m² of Canvas is required to cover the heap.
