Question

✴QUESTION:

A heap of rice is in the form of a cone of diameter 12m and height 8m .Find its volume.How much canvas cloth is required to cover the heap?(Use π= 3.14)?

Answer 1

Step-by-step explanation:

given

• diameter to the base of a cone is = 12 m 
• height of cone = 8m 
• volume of cone = ?

ATQ

diameter of base = 12 m

=> radius of base = 12 / 2 = 6 m

volume of cine is = 1/3 ×π ×r² ×h

=> 1/3 × 22 / 7 × 6² ×8 

=> 36×22×8 /21 

=> 6336 / 21

= 301.71 m³
