1.	b) A heap of a rice is in the form of a cone of diameter 12 mt and height 8 mt.Find its volume? How much canvas cloth is required to cover the heap?(Use T 3.14)
Answer» Diameter to the base of a cone is = 12 mandheight of cone = 8m we have to find:volume of cone = ? solution:-According to givendiameter of base = 12 m=> radius of base = 12 / 2 = 6 m we know that;volume of cine is = 1/3 ×π×r²×h => 1/3× 22 / 7× 6²×8 => 36×22×8 /21 => 6336 / 21 = 301.71 m³ Answer

Answer»

Diameter to the base of a cone is = 12 mandheight of cone = 8m

we have to find:volume of cone = ?

solution:-According to givendiameter of base = 12 m=> radius of base = 12 / 2 = 6 m

we know that;volume of cine is = 1/3 ×π×r²×h

=> 1/3× 22 / 7× 6²×8

=> 36×22×8 /21

=> 6336 / 21

= 301.71 m³ Answer
