Question

A heap of wheat is in form of cone whose diameter is 10 and height is 3m find it volume of 1cm³ wheat cost is ₹ 10, then find the total cost

Answer 1

Diameter of cone = 10.5 m

Radius of cone (r) = 5.25 m

Height of cone (h) = 3 m

Volume of cone = 1 / 3 πr2h

= 1 / 3 × 22 / 7 × 5.25 × 5.25 × 3

= 86.625m3

Cost of 1m3 of wheat = 10

∴ Cost of 86.625 m3 of wheat = 10 × 86.625

= 86.625
